As you all know on this new blog I try to fix all issues with the PPSSPP application and games, so I went to Google's questionhub for frequently asked questions on the PPSSPP and this is what I found so I'll be answering the questions today.
If you have a PPSSPP game you could just send the ISO or cso through xender along with the PPSSPP application, then open the application go to your xender/other folder in the PSP application should find the image of the game there just click on it and enjoy
