Unpack *.XCI base game patched with *.NCA update that was already inside *.XCI Unpack *.XCI base game patched with *.NSP update Unpack *.NSP base game patched with *.NSP update Tool doesn't support putting titlekey manually and never will. Tools for easy unpacking files are hard to find and didn't work for me. I made this tutorial with my own *.cmd file. You can apply IPS and dip-switch now and press P to continue.EDIT: THIS TUTORIAL IS OUTDATED! NO SUPPORT! You can also disassemble CPU ROMs with the M68000 debugger and Z80 debugger functions in CPS1.NET. ROM hackers can focus on the real address-value pair and neglect ROM encoding and decoding. So the IPS file (.cht extension, the same as cheat file) is easy to understand. There is no combination of multiple ROMs, no CPS1 graphic effects decoding, no Kabuki decoding, and no byte swap. You can open and disassemble maincpu.rom and audiocpu.rom (only CPS-1 board) with IDA Pro directly. The ROM format of CPS1.NET is the simplest. My former project M1.NET tells you how to dump these sound related ROMs from running MAME. The program loads the file qsound.rom as the Q-Sound chip ROM. Since there is Q-Sound bank switch, the upper limit size of audiocpu.rom is 0x50000 bytes. The program loads the file audiocpu.rom as the Z80 ROM for ReadMemory only, the file audiocpuop.rom as the Z80 ROM for ReadOp only. You can dump the certain memory of running MAME directly to make gfx.rom.įor CPS-1 board, the Z80 CPU runs at 3579545 Hz, and there are two sound chips: Yamaha YM2151, Oki MSM6295.įor CPS-1(QSound) board, the Z80 CPU runs at 8MHz with Kabuki encrypted code, and there is a Q-Sound chip. Size of maincpu.rom should be no greater than 0x400000 bytes. The program loads the file maincpu.rom as M68000 ROM. There are total 6 types of ROM: maincpu.rom, gfx.rom, audiocpu.rom, audiocpop.rom, oki.rom and qsound.rom. Timer callbacks contains: video update, soft reset, M68000 interrupt, Z80 interrupt, set sound latched value, sound update, YM2151 interrupt.īy these steps, CPS1.NET emulates the CPS1 board successfully.ĬPS1.NET has more functions: save and load state, record and replay input, cheat, cheat search, IPS (patch M68000 ROM), CPS1 debugger, M68000 debugger, Z80 debugger. The cpuexectimeslice operation means execute M68000 CPU for a time slice, execute Z80 CPU for a time slice, and execute timer callbacks. I set the transparent color to magenta to show more background detail. I maximize the default visible area to 512512 pixels, so you can see more details (for example: the hanging sword). You can do anything about arcade games with MAME source code.ĬPS1.NET is a C based CPS1 emulator, and it maintains the same architecture of MAME. Its main purpose is to be a reference to the inner workings of the emulated arcade machines. Mame Sprite Extractor How To Dump These.
