User guide

About supported ROM sets:

This homebrew conforms to MAME (Multiple Arcade Machine Emulator) 0.120, the ZIP file name is the rom required by MAME 0.120 must match the set name.

All rom files should be compressed into a ZIP file. It is exactly the same as MAME, except that it cannot handle the files expanded in the folder. Also, it does not support rom sets that MAME does not support.

The rom file name in the ZIP file can be any name, but CRC must match the CRC of the MAME 0.120 rom set. All games displayed in white on the file browser will work.

A list of supported games along with the rom names can be found in gamelist_cps1.txt.

Note: You may match MAME 0.120 and later rom sets using tools such as ClrMame Pro and RomCenter.

Changelog

v2.3.1 Development version

Although it is the latest release, code prior to 2.2.x is used since it is a development version.
Supports communication play with AdHoc as standard (excluding NCDZPSP).
Use SystemButtons.prx, which is an extension of homehook.prx. (also used in 1.5 Kernel version). When you are using CFW 3.52 or higher, it corresponds to the volume display when the VOL +/- button is pressed.
Sound emulation processing is different.
The video emulation processing of MVS and NCDZ is different.
Since the free memory is reduced due to the addition of functions, it is possible to create a cache file. More games are needed. Also, some games may not start.
Since the screen update interval is adjusted to the PSP refresh rate, it becomes earier to synchronize with VBLANK. However in MVS, the game progresses at a faster speed than the actual machine (though it is not noticeable).
