- Nametable RAM is now 2K, except for the two games (Rad Racer II, Gauntlet) that have extra RAM on daughter boards.
- Removed unnecessary overridden machine/video start code for PinBot.
- Added an address map for the PPU.
- Further simplified initialization code for games that have VRAM or special RP5H01 usage.
- Lots of conversion to C++-style comments with a few corrections along the way.
|
|
|
|
|
| |
- Modernized PRG ROM banking.
- Cleaned up cart daughter board initialization code.
- Fixed daughter board RAM sizes for Baseball Star, Pinbot, and Punch-Out. Punch-Out's is NVRAM and it now saves properly.

- Limited light detection to scanlines recently drawn by CRT.
- Lowered light detection threshold to better reflect how real zapper behaves; color doesn't need to be white.
- Bugs fixed:
* not detecting hits on certain white objects
* misdetecting hits on objects far away from the pointer
* not being able to track where zapper is pointed in demo/test software

API impact:
- install_ram/rom/writeonly now requires a non-null pointer. If you want
automatically managed ram, add it to a memory map, not in machine_start
- install_*_bank now requires a memory_bank *, not a string
- one can create memory banks outside of memory maps with memory_bank_creator
- one can create memory shares outside of memory maps with memory_share_creator
Memory maps impact:
- ram ranges with overlapping addresses are not shared anymore. Use .share()
- ram ranges touching each other are not merged anymore. Stay in your range
Extra note:
- there is no need to create a bank just to dynamically map some memory/rom.
Just use install_rom/ram/writeonly

* Basically, initialisers go in the constructor arguments, and things for setting format go in set_format.
* Initialisation patterns can be specified with an enum discriminator or with a FUNC and optionally a tag.
* Formats can be specified with an enum discriminator or a size and function pointer.
* You must always supply the number of entries when setting the format.
* When initislising with a paletter initialisation member, you can specify the entries and indirecte entries together.
* The palette_device now has a standard constructor, so use .set_entries if you are specifying entry count with no format/initialisation.
* Also killed an overload on delegates that wasn't being useful.

Input and screen tags are now resolved relative to a layout's owner
device.
Easy way to demonstrate is with: mame64 intlc440 -tty ie15
Previously you'd only get the IE15 terminal's layout and you'd be unable
to use the INTELLEC 4/40 front panel. Now you'll get the choice of
layouts from both the system and the terminal device in video options.

There are multiple issues with the current device callbacks:
* They always dispatch through a pointer-to-member
* Chained callbacks are a linked list so the branch unit can't predict the early
* There's a runtime decision made on the left/right shift direction
* There are runtime NULL checks on various objects
* Binding a lambda isn't practical
* Arbitrary transformations are not supported
* When chaining callbacks it isn't clear what the MCFG_DEVCB_ modifiers apply to
* It isn't possible to just append to a callback in derived configuration
* The macros need a magic, hidden local called devcb
* Moving code that uses the magic locals around is error-prone
* Writing the MCFG_ macros to make a device usable is a pain
* You can't discover applicable MCFG_ macros with intellisense
* Macros are not scoped
* Using an inappropriate macro isn't detected at compile time
* Lots of other things
This changeset overcomes the biggest obstacle to remving MCFG_ macros
altogether. Essentially, to allow a devcb to be configured, call
.bind() and expose the result (a bind target for the callback). Bind
target methods starting with "set" repace the current callbacks; methods
starting with "append" append to them. You can't reconfigure a callback
after resolving it. There's no need to use a macro matching the
handler signatures - use FUNC for everything. Current device is implied
if no tag/finder is supplied (no need for explicit this).
Lambdas are supported, and the memory space and offset are optional.
These kinds of things work:
* .read_cb().set([this] () { return something; });
* .read_cb().set([this] (offs_t offset) { return ~offset; });
* .write_cb().set([this] (offs_t offset, u8 data) { m_array[offset] = data; });
* .write_cb().set([this] (int state) { some_var = state; });
Arbitrary transforms are allowed, and they can modify offset/mask for example:
* .read_cb().set(FUNC(my_state::handler)).transform([] (u8 data) { return bitswap<4>(data, 1, 3, 0, 2); });
* .read_cb().set(m_dev, FUNC(some_device::member)).transform([] (offs_t &offset, u8 data) { offset ^= 3; return data; });
It's possible to stack arbitrary transforms, at the cost of compile
time (the whole transform stack gets inlined at compile time). Shifts
count as an arbitrary transform, but mask/exor does not.
Order of mask/shift/exor now matters. Modifications are applied in the
specified order. These are NOT EQUIVALENT:
* .read_cb().set(FUNC(my_state::handler)).mask(0x06).lshift(2);
* .read_cb().set(FUNC(my_state::handler)).lshift(2).mask(0x06);
The bit helper no longer reverses its behaviour for read callbacks, and
I/O ports are no longer aware of the field mask. Binding a read
callback to no-op is not supported - specify a constant. The GND and
VCC aliases have been removed intentionally - they're TTL-centric, and
were already being abused.
Other quirks have been preserved, including write logger only logging
when the data is non-zero (quite unhelpful in many of the cases where
it's used). Legacy syntax is still supported for simple cases, but will
be phased out. New devices should not have MCFG_ macros.
I don't think I've missed any fundamental issues, but if I've broken
something, let me know.

- PULSE_LINE is no longer a value. Existing uses have been changed to pulse_input_line with attotime::zero as the second argument.
- Formerly only INPUT_LINE_NMI and INPUT_LINE_RESET were allowed with PULSE_LINE. INPUT_LINE_NMI no longer receives special handling; instead, CPU devices must specify which of their input lines are edge-triggered and thus may be used with zero-width pulses by overriding the execute_input_edge_triggered predicate. INPUT_LINE_RESET is still special-cased, however.
- execute_default_irq_vector now allows a different default vector to be specified for each input line. This added flexibility may or may not prove useful.

* Get rid of implicit prefix for GFX decode names and prefix them all
* Get rid of special macro for adding GFXDECODE in favour of constructor
* Make empty GFX decode a static member of interface
* Allow palette to be specified to GFXDECODE as a device finder
* Removed diserial.h from emu.h as it's used relatively infrequently
Also fix darkseal and vaportra propely. The palette device
automatically attaches itself to a share with matching tag. The correct
solution here is to rename one or the other out of the way, since it was
never attached to a share before.

Start replacing special device macros with additional constructors,
starting with ISA, INTELLEC 4 and RS-232 buses.
Allow an object finder to take on the target of another object finder.
(For a combination of the previous two things in action, see either the
INTELLEC 4 driver, or the Apple 2 PC Exporter card. Also check out
looping over a device finder array to instantiate devices in some
places. Lots of things no longer need to pass tags around.)
Start supplying default clocks for things that have a standard clock or
have all clocks internal.
Eliminate the separate DEV versions of the DEVCB_ macros. Previously,
the plain versions were a shortcut for DEVICE_SELF as the target. You
can now supply a string tag (relative to current device being
configured), an object finder (takes on the base and relative tag), or
a reference to a device/interface (only do this if you know the device
won't be replaced out from under it, but that's a safe assumption for
your subdevices). In almost all cases, you can get the effect you want
by supplying *this as the target.
Eliminate sound and CPU versions of macros. They serve no useful
purpose, provide no extra checks, make error messages longer, add
indirection, and mislead newbies into thinking there's a difference.
Remove a lot of now-unnecessary ":" prefixes binding things relative to
machine root.
Clean up some miscellaneous rot.

ASCII.
This has not been done unilaterally - I have the support of @galibert,
@Tafoid, and @rb6502 to do something about the current free-for-all.
The trouble with the ROM label field in MAME is that it serves multiple
competing purposes: it's supposed to identify the device in the original
system, and also act as a filename when searching for media image files
to load. It also has to appear in listings of needed/missing files
(e.g. in cases where the image _isn't_ found).
To identify the original device, the ROM label field in MAME often
contains text derived from some combination of one or more of the text
on a label if present, the silkscreen on an IC package, the location on
the circuit board, and the device designation. There's no standard for
the order in which these appear and how they're separated. Some people
add arbitrary filename extensions and other annotations.
There are practical limitations on what can appear in the string, given
it's used as a filename:
* Path/name length limits.
* Restrictions on characters that can appear in a filename.
* Practicality of using the filename in a command-line environment.
* Ambiguity when describing a filename.
Filesystems themselves typically restrict characters in filenames:
* Windows defines MAX_PATH as 260 characters - longer paths are
difficult to use with Win32 APIs and don't work properly in Windows
Explorer
* Most filesystems don't allow ^@ or the path separator in names.
* Windows doesn't allow C0 control characters or <>:"/\|?* characters in
filenames.
* Filesystems may have collation, e.g. FAT16 is case-folding, NTFS and
HFS+ are case-preserving but case-insensitive, while EXT and XFS are
case-sensitive.
* Filesystems may perform Unicode normalisation, e.g. NTFS forces NFC,
HFS+ forces NFD, while ZFS stores filenames as supplied at creation,
but may be configured to apply normalisation when testing equality.
Shells use various ASCII characters for special purposes:
* C0 control characters for line editing and control (e.g. ^C to cancel
a line, ^V for control charecter escape, ^R for history search).
* The "'\ chracaters for quoting/escaping.
* The ><| characters for redirection.
* The *?[] characters for pattern matching.
* The ${}~ characters for variable substitution/sequence expansion.
* The ! or ^ characters for history substitution.
* The ()` characters for controlling subshells.
* The %& characters for job control.
* The ; character as a command separator.
* The # character for comments.
There's also the issue of whether users across a range of locales will
be able to type/display characters. We still don't have good support
for Unicode console output on Windows (std::wcout doesn't seem to work
properly), many users don't install C/J/K fonts, and many users aren't
comfortable entering text in unfamiliar languages. This means we're
limited to printable ASCII for practical purposes.
The practical limitations mean the subset of "safe" characters is
limited to ASCII digits, either uppercase or lowercase English Latin
(but not both due to collation behaving differently across systems), and
the +,-.=_ punctuation chracters. We've decided on lowercase, digits,
and safe punctuation. In addition to this, spaces are allowed, as they
can be quoted/escaped easily enough if no other special characters are
used.
There have been some arguments that allowing uppercase is "more
accurate", but in practical terms it doesn't add much value. A string
in a C++ program can't represent layout, relative size of text, colour
and shape of the label, text font, graphics, and many other details. It
also does nothing to address labels with text outside the English Latin
alphabet (e.g. labels with Chinese ideographs). Besides missing
information, the lack of hard and fast rules means you need to intuit
what a label string in MAME is trying to represent. There is simply no
substitute for photographs. There wasn't even any consistency in case
within individual machine sets. For example, several games in
vigilant.cpp had inconsistent case for "ic" vs "IC" in designation
suffixes, and ibm6850.cpp had inconsistent case for filename extensions
withing a set. There were sets that used uppercase for text from the
label but not from the part number/PCB location, and vice versa. It was
a huge mess.
There's some merit to the idea of allowing a wider variety of characters
in the label strings in the source, and mapping to a more restricted set
when searching for files. However it creates more issues than it
solves. It would require a change to the XML output to provide both the
label and filename, and a corresponding change to external ROM
management tools. It would be impractical to do for software lists,
because it would require ROM management tools to implement the exact
same mapping algorithm as MAME.
But that aside, actually doing useful mapping would be impractical.
What would you do with C/J/K ideographs, like the chip labelled
東方不敗 (Dongfang Bubai)? There's no intuitive way to do the mapping
wtihout incluing something like Unihan data, which would add a lot of
bloat. Even the, without a language hint the Romanisation would be less
than ideal in many cases (using Chinese reading for Japanese text and
vice versa). There's still the messy issue of filesystem collation to
deal with.
We do allow full Unicode in comments in the source. If you want to
provide a more detailed description of a ROM label, that's the place for
it. You've got more characters available, and the possibility of using
mulitple lines. There are too many other competing requirements on the
label field in the ROM definitions.

There's no voodoo involved in derived machine configurations and
fragments any more. The macros were just obfuscating things at this
point.
