Shin Megami Tensei: Persona 3 Portable

Seems to load fine for me with the latest git build on Windows. You can get the latest git build from the download page. You may also want to try recopying it from your PSP.

The best way to be polite on the internet when asking for help is to do everything possible to make things easy for the person you're requesting help from. In this case, i.e. describing what device you're using (Windows, Android, etc.), looking around to see if other versions work, trying a few different settings, and briefly describing the things you've tried without writing a novel.

Anyway, if you're getting a black screen, the most likely causes are (in order of likelyhood):
* You are using settings (e.g. not the defaults, which there's a button to reset to) that make it not work.
* There's something wrong with your iso or you downloaded it somewhere and it's been hacked (we don't help people who pirate here btw, emulation isn't possible without games, so please buy them - the market needs your votes.)
* Your device is somehow unsupported (on Windows, Intel GPUs work fairly poorly due to bad drivers), which may be improved by fiddling with "buffered rendering" or "backend" (opengl/direct3d.)
* You've copied savedata or something from somewhere and the game is choking on it. This is not likely.
* There may be some unnoticed bug in PPSSPP v0.9.9.1 (though, I don't think so) that's been fixed since.
