Metal Gear Solid:Peace Walker

[4LPH4]

I played mgspw up to the point where it asked me to download the dlc which was 800 mb and it took a lot of my internal storage so i had to delete my save data and the dlc. I installed it again and tried to extract it on my micro SD card which I always do and now I open psspp again but when I tried to play it, it said that it is corrupt. A few attempts I tried but now it seems so unplayable, I tried to extract it on my internal storage but it just hangs and takes me back to my menu. If any of y'all know how to fix my problem or give tips on how to solve it, I'd appreciate it.
