* BIG update. Aaron Giles2011-03-291-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove redundant machine items from address_space and device_t. Neither machine nor m_machine are directly accessible anymore. Instead a new getter machine() is available which returns a machine reference. So: space->machine->xxx ==> space->machine().xxx device->machine->yyy ==> device->machine().yyy Globally changed all running_machine pointers to running_machine references. Any function/method that takes a running_machine takes it as a required parameter (1 or 2 exceptions). Being consistent here gets rid of a lot of odd &machine or *machine, but it does mean a very large bulk change across the project. Structs which have a running_machine * now have that variable renamed to m_machine, and now have a shiny new machine() method that works like the space and device methods above. Since most of these are things that should eventually be devices anyway, consider this a step in that direction. 98% of the update was done with regex searches. The changes are architected such that the compiler will catch the remaining errors: // find things that use an embedded machine directly and replace // with a machine() getter call S: ->machine-> R: ->machine\(\)\. // do the same if via a reference S: \.machine-> R: \.machine\(\)\. // convert function parameters to running_machine & S: running_machine \*machine([^;]) R: running_machine \&machine\1 // replace machine-> with machine. S: machine-> R: machine\. // replace &machine() with machine() S: \&([()->a-z0-9_]+machine\(\)) R: \1 // sanity check: look for this used as a cast (running_machine &) // and change to this: *(running_machine *)

* running_device -> device_t Aaron Giles2010-12-311-1/+1

* Replace "const address_space" with "address_space" throughout the system. Aaron Giles2010-08-191-1/+1
| | | | | | | | | | | The purpose of making it const before was to discourage direct tampering, but private/protected does a better job of that now anyhow, and it is annoying now. s/const[ \t]+address_space\b/address_space/g; Is basically what I did.

Do not panic; report issues to the list in the short term and I will look into them. There are probably also some details I forgot to mention. Please ask questions if anything is not clear. NOTE: This is a major internal change to the way devices are handled in MAME. There is a small impact on drivers, but the bulk of the changes are to the devices themselves. Full documentation on the new device handling is in progress at http://mamedev.org/devwiki/index.php/MAME_Device_Basics Defined two new casting helpers: [Aaron Giles] downcast<type>(value) should be used for safe and efficient downcasting from a base class to a derived class. It wraps static_cast<> by adding an assert that a matching dynamic_cast<> returns the same result in debug builds. crosscast<type>(value) should be used for safe casting from one type to another in multiple inheritance scenarios. It compiles to a dynamic_cast<> plus an assert on the result. Since it does not optimize down to static_cast<>, you should prefer downcast<> over crosscast<> when you can. Redefined running_device to be a proper C++ class (now called device_t). Same for device_config (still called device_config). All devices and device_configs must now be derived from these base classes. This means each device type now has a pair of its own unique classes that describe the device. Drivers are encouraged to use the specific device types instead of the generic running_device or device_t classes. Drivers that have a state class defined in their header file are encouraged to use initializers off the constructor to locate devices. [Aaron Giles] Removed the following fields from the device and device configuration classes as they never were necessary or provided any use: device class, device family, source file, version, credits. [Aaron Giles] Added templatized variant of machine->device() which performs a downcast as part of the device fetch. Thus machine->device<timer_device>("timer") will locate a device named "timer", downcast it to a timer_device, and assert if the downcast fails. [Aaron Giles] Removed most publically accessible members of running_device/device_t in favor of inline accessor functions. The only remaining public member is machine. Thus all references to device->type are now device->type(), etc. [Aaron Giles] Created a number of device interface classes which are designed to be mix- ins for the device classes, providing specific extended functionality and information. There are standard interface classes for sound, execution, state, nvram, memory, and disassembly. Devices can opt into 0 or more of these classes. [Aaron Giles] Converted the classic CPU device to a standard device that uses the execution, state, memory, and disassembly interfaces. Used this new class (cpu_device) to implement the existing CPU device interface. In the future it will be possible to convert each CPU core to its own device type, but for now they are still all CPU devices with a cpu_type() that specifies exactly which kind of CPU. [Aaron Giles] Created a new header devlegcy.h which wraps the old device interface using some special template classes. To use these with an existing device, simply remove from the device header the DEVICE_GET_INFO() declaration and the #define mapping the ALL_CAPS name to the DEVICE_GET_INFO. In their place #include "devlegcy.h" and use the DECLARE_LEGACY_DEVICE() macro. In addition, there is a DECLARE_LEGACY_SOUND_DEVICE() macro for wrapping existing sound devices into new-style devices, and a DECLARE_LEGACY_NVRAM_DEVICE() for wrapping NVRAM devices. Also moved the token and inline_config members to the legacy device class, as these are not used in modern devices. [Aaron Giles] Converted the standard base devices (VIDEO_SCREEN, SPEAKER, and TIMER) from legacy devices to the new C++ style. Also renamed VIDEO_SCREEN to simply SCREEN. The various global functions that were previously used to access information or modify the state of these devices are now replaced by methods on the device classes. Specifically: video_screen_configure() == screen->configure() video_screen_set_visarea() == screen->set_visible_area() video_screen_update_partial() == screen->update_partial() video_screen_update_now() == screen->update_now() video_screen_get_vpos() == screen->vpos() video_screen_get_hpos() == screen->hpos() video_screen_get_vblank() == screen->vblank() video_screen_get_hblank() == screen->hblank() video_screen_get_width() == screen->width() video_screen_get_height() == screen->height() video_screen_get_visible_area() == screen->visible_area() video_screen_get_time_until_pos() == screen->time_until_pos() video_screen_get_time_until_vblank_start() == screen->time_until_vblank_start() video_screen_get_time_until_vblank_end() == screen->time_until_vblank_end() video_screen_get_time_until_update() == screen->time_until_update() video_screen_get_scan_period() == screen->scan_period() video_screen_get_frame_period() == screen->frame_period() video_screen_get_frame_number() == screen->frame_number() timer_device_adjust_oneshot() == timer->adjust() timer_device_adjust_periodic() == timer->adjust() timer_device_reset() == timer->reset() timer_device_enable() == timer->enable() timer_device_enabled() == timer->enabled() timer_device_get_param() == timer->param() timer_device_set_param() == timer->set_param() timer_device_get_ptr() == timer->get_ptr() timer_device_set_ptr() == timer->set_ptr() timer_device_timeelapsed() == timer->time_elapsed() timer_device_timeleft() == timer->time_left() timer_device_starttime() == timer->start_time() timer_device_firetime() == timer->fire_time() Updated all drivers that use the above functions to fetch the specific device type (timer_device or screen_device) and call the appropriate method. [Aaron Giles] Changed machine->primary_screen and the 'screen' parameter to VIDEO_UPDATE to specifically pass in a screen_device object. [Aaron Giles] Defined a new custom interface for the Z80 daisy chain. This interface behaves like the standard interfaces, and can be added to any device that implements the Z80 daisy chain behavior. Converted all existing Z80 daisy chain devices to new-style devices that inherit this interface. [Aaron Giles] Changed the way CPU state tables are built up. Previously, these were data structures defined by a CPU core which described all the registers and how to output them. This functionality is now part of the state interface and is implemented via the device_state_entry class. Updated all CPU cores which were using the old data structure to use the new form. The syntax is currently awkward, but will be cleaner for CPUs that are native new devices. [Aaron Giles] Converted the okim6295 and eeprom devices to the new model. These were necessary because they both require multiple interfaces to operate and it didn't make sense to create legacy device templates for these single cases. (okim6295 needs the sound interface and the memory interface, while eeprom requires both the nvram and memory interfaces). [Aaron Giles] Changed parameters in a few callback functions from pointers to references in situations where they are guaranteed to never be NULL. [Aaron Giles] Removed MDRV_CPU_FLAGS() which was only used for disabling a CPU. Changed it to MDRV_DEVICE_DISABLE() instead. Updated drivers. [Aaron Giles] Reorganized the token parsing for machine configurations. The core parsing code knows how to create/replace/remove devices, but all device token parsing is now handled in the device_config class, which in turn will make use of any interface classes or device-specific token handling for custom token processing. [Aaron Giles] Moved many validity checks out of validity.c and into the device interface classes. For example, address space validation is now part of the memory interface class. [Aaron Giles] Consolidated address space parameters (bus width, endianness, etc.) into a single address_space_config class. Updated all code that queried for address space parameters to use the new mechanism. [Aaron Giles]
* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is now separate from runtime device state. I have larger plans for devices, so there is some temporary scaffolding to hold everything together, but this first step does separate things out. There is a new class 'running_device' which represents the state of a live device. A list of these running_devices sits in machine->devicelist and is created when a running_machine is instantiated. To access the configuration state, use device->baseconfig() which returns a reference to the configuration. The list of running_devices in machine->devicelist has a 1:1 correspondance with the list of device configurations in machine->config->devicelist, and most navigation options work equally on either (scanning by class, type, etc.) For the most part, drivers will now deal with running_device objects instead of const device_config objects. In fact, in order to do this patch, I did the following global search & replace: const device_config -> running_device device->static_config -> device->baseconfig().static_config device->inline_config -> device->baseconfig().inline_config and then fixed up the compiler errors that fell out. Some specifics: Removed device_get_info_* functions and replaced them with methods called get_config_*. Added methods for get_runtime_* to access runtime state from the running_device. DEVICE_GET_INFO callbacks are only passed a device_config *. This means they have no access to the token or runtime state at all. For most cases this is fine. Added new DEVICE_GET_RUNTIME_INFO callback that is passed the running_device for accessing data that is live at runtime. In the future this will go away to make room for a cleaner mechanism. Cleaned up the handoff of memory regions from the memory subsystem to the devices.
* Within src/emu, basic conversions: Aaron Giles2010-01-121-1/+1
| | | | | | devtag_get_device ... machine->device() memory_find_address_space ... device->space()
* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Created new central header "emu.h"; this should be included by pretty much any driver or device as the first include. This file in turn includes pretty much everything a driver or device will need, minus any other devices it references. Note that emu.h should *never* be included by another header file. - Updated all files in the core (src/emu) to use emu.h. - Removed a ton of redundant and poorly-tracked header includes from within other header files. - Temporarily changed driver.h to map to emu.h until we update files outside of the core. Added class wrapper around tagmap so it can be directly included and accessed within objects that need it. Updated all users to embed tagmap objects and changed them to call through the class. Added nicer functions for finding devices, ports, and regions in a machine: machine->device("tag") -- return the named device, or NULL machine->port("tag") -- return the named port, or NULL machine->region("tag"[, &length[, &flags]]) -- return the named region and optionally its length and flags Made the device tag an astring. This required touching a lot of code that printed the device to explicitly fetch the C-string from it. (Thank you gcc for flagging that issue!)
* NOTE: This change requires two new osd functions: osd_malloc() and Aaron Giles2010-01-081-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | osd_free(). They take the same parameters as malloc() and free(). Renamed mamecore.h -> emucore.h. New C++-aware memory manager, implemented in emualloc.*. This is a simple manager that allows you to add any type of object to a resource pool. Most commonly, allocated objects are added, and so a set of allocation macros is provided to allow you to manage objects in a particular pool: pool_alloc(p, t) = allocate object of type 't' and add to pool 'p' pool_alloc_clear(p, t) = same as above, but clear the memory first pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type 't' and add to pool 'p' pool_alloc_array_clear(p, t, c) = same, but with clearing pool_free(p, v) = free object 'v' and remove it from the pool Note that pool_alloc[_clear] is roughly equivalent to "new t" and pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also note that pool_free works for single objects and arrays. There is a single global_resource_pool defined which should be used for any global allocations. It has equivalent macros to the pool_* macros above that automatically target the global pool. In addition, the memory module defines global new/delete overrides that access file and line number parameters so that allocations can be tracked. Currently this tracking is only done if MAME_DEBUG is enabled. In debug builds, any unfreed memory will be printed at the end of the session. emualloc.h also has #defines to disable malloc/free/realloc/calloc. Since emualloc.h is included by emucore.h, this means pretty much all code within the emulator is forced to use the new allocators. Although straight new/delete do work, their use is discouraged, as any allocations made with them will not be tracked. Changed the familar auto_alloc_* macros to map to the resource pool model described above. The running_machine is now a class and contains a resource pool which is automatically destructed upon deletion. If you are a driver writer, all your allocations should be done with auto_alloc_*. Changed all drivers and files in the core using malloc/realloc or the old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros instead, or the global_alloc_* macros if necessary. Added simple C++ wrappers for astring and bitmap_t, as these need proper constructors/destructors to be used for auto_alloc_astring and auto_alloc_bitmap. Removed references to the winalloc prefix file. Most of its functionality has moved into the core, save for the guard page allocations, which are now implemented in osd_alloc and osd_free.

* Bulk change alert. Aaron Giles2009-04-261-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This update changes the way we handle memory allocation. Rather than allocating in terms of bytes, allocations are now done in terms of objects. This is done via new set of macros that replace the malloc_or_die() macro: alloc_or_die(t) - allocate memory for an object of type 't' alloc_array_or_die(t,c) - allocate memory for an array of 'c' objects of type 't' alloc_clear_or_die(t) - same as alloc_or_die but memset's the memory to 0 alloc_array_clear_or_die(t,c) - same as alloc_array_or_die but memset's the memory to 0 All original callers of malloc_or_die have been updated to call these new macros. If you just need an array of bytes, you can use alloc_array_or_die(UINT8, numbytes). Made a similar change to the auto_* allocation macros. In addition, added 'machine' as a required parameter to the auto-allocation macros, as the resource pools will eventually be owned by the machine object. The new macros are: auto_alloc(m,t) - allocate memory for an object of type 't' auto_alloc_array(m,t,c) - allocate memory for an array of 'c' objects of type 't' auto_alloc_clear(m,t) - allocate and memset auto_alloc_array_clear(m,t,c) - allocate and memset All original calls or auto_malloc have been updated to use the new macros. In addition, auto_realloc(), auto_strdup(), auto_astring_alloc(), and auto_bitmap_alloc() have been updated to take a machine parameter. Changed validity check allocations to not rely on auto_alloc* anymore because they are not done in the context of a machine. One final change that is included is the removal of SMH_BANKn macros. Just use SMH_BANK(n) instead, which is what the previous macros mapped to anyhow.
* Moved some of the CPU cores over to use get_safe_token like other devices. Aaron Giles2009-03-121-3/+3

* Fixed bug that caused 64-bit PowerPC systems to fetch opcodes in the wrong ↵ Aaron Giles2009-03-071-3/+0

* DRC frontends must do their own opcode fetching unfortunately. Updated all Aaron Giles2009-01-181-19/+0
| | | | DRC cores to do this. Also tweaked a few oddities in the SH2 DRC.
* Added new #define ENDIANNESS_NATIVE, which maps to either ENDIANNESS_LITTLE Aaron Giles2009-01-171-5/+1
| | | | | | | | | | | | | or ENDIANNESS_BIG based on the LSB_FIRST definition. Unlink LSB_FIRST, ENDIANNESS_NATIVE always exists and can be used in expressions without invoking the preprocessor. Added macro ENDIAN_VALUE_LE_BE() which selects one of two values based on the endianness passed in. Also added NATIVE_ENDIAN_VALUE_LE_BE() which calls ENDIAN_VALUE_LE_BE with ENDIANNESS_NATIVE. Updated a number of drivers and call sites to use these macros in favor of #ifdef LSB_FIRST.
* Renamed CPUINFO_PTR_* to CPUINFO_FCT_* for function get infos. Aaron Giles2008-12-191-1/+1
| | | | Changed Z80 over to the new cpu_state_table mechanism.
* More device normalization: Aaron Giles2008-12-161-1/+1
| | | | | | | | | | cpu_get_info_* -> device_get_info_* cpu_set_info_* -> device_set_info_* cpu_reset -> device_reset Removed the cputype_get_* macros as they are not necessary. Removed cpuintrf_init() which is no longer necessary.

* Converted a bunch of CPU cores over to the new memory functions. Aaron Giles2008-11-221-2/+3
|
* Converted change_pc() into a no-op. Changed memory_set_direct_region() to Aaron Giles2008-11-191-1/+1
| | | | | | | | | | | | | | return a boolean indicating whether the given address was successfully located in a bank. Change raw/decrypted access to look at this result, and if the given address is not in a bank, calls through to the standard read handlers. In theory, this should prevent crashes when accessing opcodes. It does in fact prevent mp_col3 from crashing. Fixed address space mapping handlers to invalidate direct access regions if a change is made to the mapping. This is needed to prevent the Sega dynamic memory mapping chips from falling over.
* Generalized the concept of opbase access into "direct" access. Aaron Giles2008-11-171-2/+4
| | | | | | | | Removed opbase globals to the address_space structure. Cleaned up names of pointers (decrypted and raw versus rom and ram). Added inline functions to read/write data via any address space. Added macros for existing functions to point them to the new functions. Other related cleanups.
* Added CPU device parameters to all CPU callbacks except for the Aaron Giles2008-11-101-1/+3
| | | | | | | | context ones (which are going away), the disassembler (which should have no dependencies on the live CPU), and the validity check. Removed global token from all pointer-ified CPU cores that don't have internal read/write callbacks (which still need to reference it).
* Major cpuintrf changes: Aaron Giles2008-11-101-6/+6
| | | | | | | | | | | | | | | | | | | | | | * added a set of cpu_* calls which accept a CPU device object; these are now the preferred means of manipulating a CPU * removed the cpunum_* calls; added an array of cpu[] to the running_machine object; converted all existing cpunum_* calls to cpu_* calls, pulling the CPU device object from the new array in the running_machine * removed the activecpu_* calls; added an activecpu member to the running_machine object; converted all existing activecpu_* calls to cpu_* calls, pulling the active CPU device object from the running_machine * changed cpuintrf_push_context() to cpu_push_context(), taking a CPU object pointer; changed cpuintrf_pop_context() to cpu_pop_context(); eventually these will go away * many other similar changes moving toward a model where all CPU references are done by the CPU object and not by index
* Populated tag and static_config parts of fake CPU device. Removed 'config' Aaron Giles2008-11-091-0/+1

| | | | | | | | | | | | | | | | * changed from tracking "live" registers to tracking "necessary" registers * genericized register tracking to be more flexible * added previous instruction pointer to opcode descriptions PowerPC frontend/DRC: * cleaned up register tracking implementation * fixed numerous errors and shortcomings in the tracking * added support for removing unnecessary XER CA and CR0 computations * updated UML logging to output new frontend statistics MIPS3 frontend/DRC: * tweaked register tracking to match new DRC frontend system * updated UML logging to output new frontend statistics
* PowerPC dynamic recompiler: [Aaron Giles] Aaron Giles2008-06-051-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - rewrote PowerPC implementation as a dynamic recompiler on top of the universal recompiler engine - wrote a front-end to analyze PowerPC code paths and register usage - wrote a common shared module with C implementations of tricky CPU behaviors - added separate CPU types for the variants supported, instead of relying on a hidden model enum - rewrote the serial port emulation for the 4xx series to be more accurate and not rely on separate DMA handlers - rewrote the MMU handling to implement a software TLB that faults in pages and handles changed bits appropriately - implemented emulation of the PowerPC 603's software TLB, which allows the model 3 games to run without a hack to disable the MMU Updated the PowerPC disassembler to share constants with the rest of the core, and to more aggressively use simplified mnemonics, especially for branches. [Aaron Giles] Universal recompiler: - fixed frontend to handle opcode widths different from bus width - added several new opcodes: * (D)GETFLGS - copies the UML flags to a destination operand * FDRNDS - rounds a double precision value to single precision - renamed several opcodes: * SETC -> CARRY * XTRACT -> ROLAND * INSERT -> ROLINS - consolidated the following opcodes: * LOAD?U -> LOAD * LOAD?S -> LOADS * STORE? -> STORE * READ?U -> READ * READ?M -> READM * WRITE? -> WRITE * WRITM? -> WRITEM * SEXT? -> SEXT * FTOI?? -> FTOINT * FFRI? -> FFRINT * FFRF? -> FFRFLT - removed some opcodes: * FLAGS - can be done with GETFLGS/LOAD4/ROLINS * ZEXT - can be achieved with AND * READ?S - can be achieved with READ/SEXT - updated C, x86, and x64 back-ends to support these opcode changes - updated disassembler to support these opcode changes MIPS3 dynamic recompiler: - updated to use new/changed opcode forms - changed context switch so that it only swaps a single pointer Konami Hornet changes: [Aaron Giles] - updated to new PowerPC configurations - updated some memory handlers to be native 8-bit handlers - cleaned up JVS implementation to work with new serial code - added fast RAM for the work RAM to give a small speed boost Konami GTI Club changes: [Aaron Giles] - updated to new PowerPC configurations - updated some memory handlers to be native 8-bit handlers Konami Viper/ZR107 changes: [Aaron Giles] - updated to new PowerPC configurations Sega Model 3 changes: [Aaron Giles] - updated to new PowerPC configurations - reimplemented/centralized interrupt handling - these games are broken for the moment Fixed crasher due to some Konami games using 8 layers in the K056832 implementation, even though it was only written for 4. [Aaron Giles] Added fisttp opcode to i386 disassembler. [Aaron Giles]

| | | | | | | | | | | | | | | | | | | | | | | | 1. In the MIPS core: - renamed struct mips3_config -> mips3_config - updated all drivers to the new names - removed MIPS3DRC_STRICT_COP0 flag, which is no longer used - a few minor cleanups 2.

In the UML: - added new opcode SETC to set the carry flag from a source bit - added new opcode BSWAP to swap bytes within a value - updated C, x86, x64 back-ends to support the new opcodes - updated disassembler to support the new opcodes 4. In the DRC frontend: - fixed bug in handling edge case with the PC near the 0 or ~0

* Numerous MIPS3 DRC updates: Aaron Giles2008-05-191-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fixed front-end so that virtual no-op instructions are still targeted as branch targets. * Fixed front-end to mark the beginning of each sequence as needing TLB validation, since any sequence can be jumped to from anywhere. * Redid the MIPS3 TLB implementation. Fixed the exception vector and type handling. Changed the bitfields to directly map from the MIPS TLB format. Added distinction between TLB fill and TLB valid/modified exceptions. * Added separate modes for user, supervisor, and kernel modes. Each mode does proper verification of addresses now and generates address errors for invalid accesses. * Fixed several bugs in the TLB implementation; not everything works yet but it's a lot closer. * Made COP0 access checking mandatory in non-kernel modes. * Fixed several crashes when recompiling virtual no-ops. * Fixed TLB bug where entries for virtual address 0 were present by default. * Fixed bug in the map variable implementation that would sometimes result in incorrectly recovered values.
* Added a quick & dirty attempt at implementing tlb_mismatch. It's likely wrong, Aaron Giles2008-05-161-2/+2

* New universal dynamic recompiler system. The central module Aaron Giles2008-05-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | is drcuml.c, which defines a universal machine language syntax that can be generated by a frontend recompiler and then retargeted via a generic backend interface to any of a number of different architectures. A disassembler for the UML is also included to allow examination of the generated UML code. Currently supported backend architectures include 32-bit x86, 64-bit x86, and a platform-neutral interpreted C backend that can be used as a fallback for platforms without native support. The C backend also performs additional validation to ensure assumptions are met. Along with the new architecture is a new MIPS III/IV recompiler frontend. This frontend has been rewritten from the old x64-specific recompiler to generate UML opcodes instead. This means that the single recompiler can be used to target multiple backend architectures and should in theory produce identical results across all of them. The old 32-bit and 64-bit MIPS recompilers are now officially retired. The new system provides similar performance (within 5% generally) to the old system and has similar compatibility. The only currently known issues are some problems with the two Gauntlet 3D games.
* Normalized function pointer typedefs: they are now all Aaron Giles2008-03-031-3/+3
| | | | | | | | | | suffixed with _func. Did this throughout the core and drivers I was familiar with. Fixed gcc compiler error with recent render.c changes. gcc does not like explicit (int) casts on float or double functions. This is fracking annoying and stupid, but there you have it.
* Copyright cleanup: Aaron Giles2008-01-061-1/+1
| | | | | | - removed years from copyright notices - removed redundant (c) from copyright notices - updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
* Initial checkin of MAME 0.121.mame0121 Aaron Giles2007-12-171-0/+520
