For a detailed description of the Neo-Geo hardware, please visit his page at: http://cgfm2.emuviews.com/txt/mvstech.txt * Presented to you by the Shin Emu Keikaku team. * The following people have all spent probably far too much time on this: AVDB Bryan McPhail Fuzz Ernesto Corvi Andrew Prime Zsolt Vasvari Known driver issues/to-do's: ============================ * Fatal Fury 3 crashes during the ending - this doesn't occur if the language is set to Japanese, maybe the English endings are incomplete / buggy? * Graphical Glitches caused by incorrect timing? - Some raster effects are imperfect (off by a couple of lines) * 68000 waitstates on ROM region access, determined by jumpers on cart (garou train stage 3 background bug is probably related to this) Confirmed non-bugs: * Bad zooming in the Kof2003 bootlegs - this is what happens if you try and use the normal bios with a pcb set, it looks like the bootleggers didn't care. * Glitches at the edges of the screen - the real hardware can display 320x224 but most of the games seem designed to work with a width of 304, some less. * Distorted jumping sound in Nightmare in the Dark * Ninja Combat sometimes glitches ***************************************************************************** The Neo-Geo Multi Video System (MVS), is an arcade system board, being the first product in the Neo-Geo family, designed by Alpha Denshi(ADK) and released in 1990 by SNK. It was known to the coin-op industry, and offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace (games for the Neo-Geo are cartridge based and are easily exchangeable). It comes in many different cabinets but basically consists of an add on board that can be linked to a standard Jamma system. The system was discontinued in 2004.

Apollo69 10/19/99 ***************************************************************************** Watchdog: ========= The watchdog timer will reset the system after ~0.13 seconds. By cgfm's research, exactly 3,244,030 cycles (based on 24MHz clock). Newer games force a reset using the following code (this from kof99): 009CDA 203C 0003 0D40 MOVE.L #0x30D40,D0 009CE0 5380 SUBQ.L #1,D0 009CE2 64FC BCC.S *-0x2 [0x9CE0] Note however that there is a valid code path after this loop. The watchdog is used as a form of protection on a number of games, previously this was implemented as a specific hack which locked a single address of SRAM. What actually happens is if the game doesn't find valid data in the backup ram it will initialize it, then sit in a loop. The watchdog should then reset the system while it is in this loop. If the watchdog fails to reset the system the code will continue and set a value in backup ram to indiate that the protection check has failed. **************************************************************************** Mahjong Panel notes (2009-03 FP): ================================= * In Service Mode menu with mahjong panel active, controls are as follows: A = select / up (for options) B = down (for options) C = go to previous menu E = up (for menu entries) F = down (for menu entries) G = left (for options) H = right (for options) * These only work with Japanese BIOS, but I think it's not a bug: I doubt other BIOS were programmed to be compatible with mahjong panels **************************************************************************** AES driver (home version of MVS) Current emulation status: - Cartridges run. - Riding Hero runs in slow-mo due to the unemulated comm link MCU in the cartridge. In MAME if dip SW6 is set to ON to enable link play, it runs the same way! On AES there are no dipswitches, and so it always tries to talk to the MCU. ****************************************************************************/ #include "emu.h" #include "includes/neogeo.h" #include "machine/nvram.h" #include "machine/watchdog.h" #include "softlist.h" #include "neogeo.lh" #define LOG_VIDEO_SYSTEM (0) #define LOG_MAIN_CPU_BANKING (0) #define LOG_AUDIO_CPU_BANKING (0) /************************************* * * Main CPU interrupt generation * *************************************/ // The display counter is automatically reloaded with the load register contents on scanline 224, // 1146 mclks from the rising edge of /HSYNC. #define NEOGEO_VBLANK_RELOAD_HTIM (attotime::from_ticks(1146, NEOGEO_MASTER_CLOCK)) #define IRQ2CTRL_ENABLE (0x10) #define IRQ2CTRL_LOAD_RELATIVE (0x20) #define IRQ2CTRL_AUTOLOAD_VBLANK (0x40) #define IRQ2CTRL_AUTOLOAD_REPEAT (0x80) void neogeo_state::adjust_display_position_interrupt_timer() { attotime period = attotime::from_ticks((UINT64)m_display_counter + 1, NEOGEO_PIXEL_CLOCK); if (LOG_VIDEO_SYSTEM) logerror("adjust_display_position_interrupt_timer current y: %02x current x: %02x target y: %x target x: %x\n", m_screen->vpos(), m_screen->hpos(), (m_display_counter + 1) / NEOGEO_HTOTAL, (m_display_counter + 1) % NEOGEO_HTOTAL); m_display_position_interrupt_timer->adjust(period); } void neogeo_state::set_display_position_interrupt_control(UINT16 data) { m_display_position_interrupt_control = data; } void neogeo_state::set_display_counter_msb(UINT16 data) { m_display_counter = (m_display_counter & 0x0000ffff) | ((UINT32)data << 16); if (LOG_VIDEO_SYSTEM) logerror("PC %06x: set_display_counter %08x\n", m_maincpu->pc(), m_display_counter); } void neogeo_state::set_display_counter_lsb(UINT16 data) { m_display_counter = (m_display_counter & 0xffff0000) | data; if (LOG_VIDEO_SYSTEM) logerror("PC %06x: set_display_counter %08x\n", m_maincpu->pc(), m_display_counter); if (m_display_position_interrupt_control & IRQ2CTRL_LOAD_RELATIVE) { if (LOG_VIDEO_SYSTEM) logerror("AUTOLOAD_RELATIVE "); adjust_display_position_interrupt_timer(); } } void neogeo_state::update_interrupts() { m_maincpu->set_input_line(3, m_irq3_pending ?

The Universe bios roms are supported because they're now used on enough PCBs to be considered 'in active arcade use' rather than just homebrew hacks. Some may be missing, there have been multiple CRCs reported for the same revision in some cases (the Universe bios has an option for entering / displaying a serial number; these should be noted as such if they're added). Universe bios prior to version 1.3 was incompatible with AES. The 'japan-hotel' BIOS is a dump of an MVS which could be found in some japanese hotels. it is a custom MVS mobo which uses MVS carts but it hasn't jamma connector and it's similar to a console with a coin mechanism, so it's a sort of little coin op console installed in hotels. The sp-45.sp1 bios is the latest 'ASIA' revision. Japan-j3.bin is the latest 'JAPAN' revision. Both of them are also used in the sp-4x.sp1 bios of the Jamma PCB boards. The current Neo-Geo MVS system set (SFIX/SM1/000-LO) used is from a NEO-MVH MV1FS board. Other boards (MV1xx / MV2x / MV4x /MV6x) other system sets?
