Introduction

Arcade is popular in the 1990s. There are many classic arcade games released on famous system boards. For example: Street Fighter II': Champion Edition on CPS-1 board, Cadillacs and Dinosaurs on Capcom CPS-1 (Qsound) board, The King of Fighters series on Neo Geo board, Tank Force on Namco System 1 board... There are some emulators to emulate it: MAME, WinKawaks, Nebula, FBA...

The sound of arcade is amazing too. I have found the only software named M1 to reproduce the music of arcade games. M1 lets you enjoy music from over 1900 arcade games. But M1 is not an open source software.

MAME is strictly a non-profit project. Its main purpose is to be a reference to the inner workings of the emulated arcade machines. You can do anything about arcade games with MAME source code. To show the details of decrypting arcade game audio, I programmed this software named M1.NET .

How It Works?

M1.NET supports the following arcade system boards: M72, M92, Taito, Taibo B, Capcom, CPS-1, CPS-1(Qsound), CPS2, Data East, Tehkan, Konami 68000, Neo Geo, Namco System 1.

There are 2 CPUs working in Irem M72 board: a NEC V30 CPU and a Zilog Z80 CPU. There are 20-bits address and 16-bits data in V30. There are 16-bits address and 8-bits data in Z80. The V30 CPU runs at 8MHz. The program loads the file "maincpu.rom" as V30 ROM. The Z80 CPU runs at 3579545 Hz. The program loads the file "soundcpu.rom" as Z80 ROM. There are two sound chips: Yamaha YM2151, DAC chip.

There are 2 CPUs working in Irem M92 board: a NEC V33 CPU and a NEC V30 CPU. There are 20-bits address and 16-bits data in both CPUs. The V30 CPU runs at 7159090 Hz. The program loads the file "soundcpu.rom" as V30 ROM. There are two sound chips: Yamaha YM2151, Irem GA20.

For Taito board, there are various CPU and chip settings. There are relevant sound chips: General Instrument AY8910, Yamaha YM2203, Yamaha YM3526.

For Taito B board, the Z80 CPU runs at 4MHz, and there are two sound chips: General Instrument AY8910, Yamaha YM2610. The program loads the file "audiocpu.rom" as the Z80 ROM, the file "ymsnd.rom" and the optional file "ymsnddeltat.rom" as the Yamaha YM2610 ROM.

For Capcom board, there are various CPU and chip settings.

For CPS-1, the Z80 CPU runs at 3579545 Hz, and there are two sound chips: Yamaha YM2151, Oki OKI6295. The program loads the file "audiocpu.rom" as the Z80 ROM, file "oki.rom" as the OKI6295 ROM. Then the Z80 CPU runs.

For CPS-1(Qsound) and CPS2, the Z80 CPU runs at 8000000 Hz, and there is a Q-Sound chip. CPS-1(Qsound) encrypted the Z80 the code with Kabuki. The program loads the file "audiocpu.rom" as the Z80 ROM for ReadMemory only, file "audiocpuop.rom" as the Z80 ROM for ReadOp only. CPS2 loads the file "audiocpu.rom" as the Z80 ROM. CPS-1(Qsound) and CPS2 load the file "qsound.rom" as the Q-Sound chip ROM.

For Data East board, the M6502 CPU runs at 1500000Hz, and there are four sound chips: General Instrument AY8910, Yamaha YM2203, Yamaha YM3812, Oki MSM5205.

For Tehkan board, the Z80 CPU runs at 3072000Hz, and there are 3 General Instrument AY8910 sound chips.

For Konami 68000 board, there are various CPU and chip settings. There are relevant sound chips: Yamaha YM2151, Konami K007232, Konami K053260, Konami K054539, NEC UPD7759.

FOR Neo Geo, the Z80 CPU runs at 4000000 Hz, and there are two sound chips: General Instrument AY8910 and Yamaha YM2610. The program loads the file "audiocpu.rom" as the Z80 ROM, file "ymsnd.rom" and optional file "ymsnddeltat.rom" as the YM2610 ROM.

FOR Namco System 1, there are two CPUs work about sound: a Motorola M6809 CPU and a Hitachi HD63701 CPU. The two CPUs run at 1536000 Hz. There are three sound chips: Yamaha YM2151, Namco CUS30 and DAC. The program loads the file "audiocpu.rom" as the M6809 ROM, files "voice.rom" and "cus64-64a1.mcu" as the HD63701 ROM.

When you double click the track or click the play button, the function PlayDelegate, StopDelegate, StopAndPlayDelegate is triggered. By examining the running MAME, I find detail of the functions. The files "emu\Inptport.cs", "mame\cps\CPS.cs", "mame\neogeo\Neogeo.cs" and "mame\namcos1\Namcos1.cs" show the detail.

The program uses the same .lst file as M1, and it uses the truncated format of the file "m1.xml" of BridgeM1. You should install Microsoft .NET Framework 3.5 or higher before running the program. The UI is simple and it has the similar function as BridgeM1. I’ve added some .lst files. You can edit "m1.xml", .lst files and make ROMs for any game to get its audio.

Make the ROMs

Now I explain how to make the roms for both boards.
For CPS-1 game "ffight", I will make the following files: "audiocpu.rom", "oki.rom". From the MAME CPS1 code:
https://github.com/mamedev/mame/blob/master/src/mame/drivers/cps1.cpp.
Find the following code:

/* B-Board 89624B-3 */
ROM_START( ffight )
…
    ROM_REGION( 0x18000, "audiocpu", 0 ) /* 64k for the audio CPU (+banks) */
    ROM_LOAD( "ff_09.12b", 0x00000, 0x08000, 
    CRC(b8367eb5) SHA1(ec3db29fdd6200e9a8f4f8073a7e34aef731354f) )
    ROM_CONTINUE(          0x10000, 0x08000 )
 
    ROM_REGION( 0x40000, "oki", 0 ) /* Samples */
    ROM_LOAD( "ff_18.11c", 0x00000, 0x20000, 
    CRC(375c66e7) SHA1(36189e23209ce4ae5d9cbabd1574540d0591e7b3) )
    ROM_LOAD( "ff_19.12c", 0x20000, 0x20000, 
    CRC(1ef137f9) SHA1(974b5e72aa28b87ebfa7438efbdfeda769dedf5e) )
…
ROM_END

Insert 0x8000 zero bytes at offset 0x8000 of file "ff_09.12b" (or other name in previous version, just check the CRC32 b8367eb5 to confirm the file), and save it as file "audiocpu.rom" with the length 0x18000. Simply sequentially concatenate the files "ff_18.11c", "ff_19.12c" to a file "oki.rom" with the length 0x40000. You can do it with WinHex easily.

For Capcom QSound (CPS version) game "wof", so I will make the following files: "audiocpu.rom", "audiocpuop.rom", "qsound.rom". Find the following code from the MAME CPS1 code:

/* B-Board 91635B-2 */
ROM_START( wof )
…
    ROM_REGION( 0x28000, "audiocpu", 0 ) /* QSound Z80 code */
    ROM_LOAD( "tk2_qa.5k",   0x00000, 0x08000, 
    CRC(c9183a0d) SHA1(d8b1d41c572f08581f8ab9eb878de77d6ea8615d) )
    ROM_CONTINUE(          ; 0x10000, 0x18000 )
 
    ROM_REGION( 0x200000, "qsound", 0 ) /* QSound samples */
    ROM_LOAD( "tk2-q1.1k",   0x000000, 0x80000, 
    CRC(611268cf) SHA1(83ab059f2110fb25fdcff928d56b790fc1f5c975) )
    ROM_LOAD( "tk2-q2.2k",   0x080000, 0x80000, 
    CRC(20f55ca9) SHA1(90134e9a9c4749bb65c728b66ea4dac1fd4d88a4) )
    ROM_LOAD( "tk2-q3.3k",   0x100000, 0x80000, 
    CRC(bfcf6f52) SHA1(2a85ff3fc89b4cbabd20779ec12da2e116333c7c) )
    ROM_LOAD( "tk2-q4.4k",   0x180000, 0x80000, 
    CRC(36642e88) SHA1(8ab25b19e2b67215a5cb1f3aa81b9d26009cfeb8) )
…
ROM_END

Simply sequentially concatenate the files "tk2-q1.1k", "tk2-q2.2k", "tk2-q3.3k", "tk2-q4.4k" to a file "qsound.rom" with the length 0x200000. By debugging MAME, you can set a breakpoint at the end of function "kabuki_decode" in source file "src\mame\machine\kabuki.c" and find the start address, then dump the memory to file:

Or you can do the same as type CPS-1 for file "audiocpu.rom". Then dump memory from running process (for example: MAME, WinKawaks, Nebula, FBA, BridgeM1…) when ROMs loaded by finding key bytes and replace the first 0x8000 bytes of file "audiocpu.rom". And dump memory for "audiocpuop.rom" with the length 0x8000.

Conclusion

I've finished M1.NET. It figures out how the audio ROMs work. You can make any other games supported. By the translation from C to C#, there is no unsafe code and the code is much more readable. I've preserved the main architecture of MAME. Programmers can do more refer to this. For example: make it support other sound chips, program an emulator like WinKawaks...
