Support PSP games
Since we now have OpenGL support in retro-gtk, the one big blocker is gone, so now we need to "just":
- List the games
- Find a core
There aren't that many cores for PSP, in fact the only one atm is PPSSPP, so we would use that. The question is whether it requires firmware.
For listing the games we need to research:
- Can there be games on multiple disks?
- If yes, we'd need a database similarly to the one we have for PSX
- How can we distinguish these ISOs from the other platforms like PSX, Sega CD, TurboGrafx-CD etc.
