Does this emulator can play UNDUB games ?

[mr.chya]

Just to make it as clear as possible what VSUB_ is asking is if your version of the undub is working on your own PSP as it is very possible something went wrong during the patching process. So if the undub is unplayable on your actual PSP then you will likely have to patch the original game again. Also I provided a link to the compatibility list because you said you were having issues with multiple games and the quickest way to find out if a game is even playable on PPSSPP is to check if it's listed as playable. Please note however that as the builds for PPSSPP are constantly being updated you may actualy need to check in a games thread to find out which specific version supports the game you are trying to play and what settings to use.
