Features

[LunaMoo]

PPSSPP is open source, you can freely fork it and create those features yourself.

Bear in mind that PPSSPP is high level emulator and features you want are requiring low level emulator as such they will not be an easy addition. You'd have to redesign the whole project, make it emulate hardware itself not software as it does now, it also means it will likely be much slower and much less suitable for mobile hardware, possibly even limited to gaming desktops.

And no you aren't the only person who would like such features, but also you will join the rest of those people who aren't able to do what you'd have to do to make it reality as PPSSPP as a project went in completely different direction from the start and 99,9% of it's userbase that understand cons and pros of both ways wouldn't even want it to be any different.

PPSSPP exists to enhance and play PSP games even on a reasonably low level hardware. If you'd like a more vanilla-like experience that requires much more powerful desktop PC you can try jpcsp or just buy real PSP as that's the only way for purists that aren't into games and want full experience with all it's outdated stuff.
