I’m starting to use RetroArch and I’ve seen that is a very good emulator platform. My principal problem is space, so I want to have the games using the less space posible. I’ve found that PSX games are compatible with Mame CHD (that is very good because use lzma) and I’ve tried to use the same compressión for PSP games to see if I can use it. The tool is able to compress the ISO and reduce it size a lot, but PPSSPP is not able to read that files so my question is: Is possible to add CHD support to PPSSPP?
Another thing I’ve seen is that the program can read CSO and 7z files, but is unable to scan the roms that are in those formats so would be great to have support for scan that roms, because the format uses much less space in some cases.
