Weird problem when running backups on 3.90 M33-3

[Mcdohl]

I just recently got a PSP slim and am running 3.90 M33-3 on it. I decided to make a few back ups of my games, however I am encountering some wierd problems. When i make an ISO of the UMD and place it in the ISO folder, it allows me to begin the game by going games>"game I wanted" the screen goes to the PSP screen and then goes black and resets.

When I turn them into a CSO and try to run them the screen goes black and just stays there.

When I try to run a psx after converting it through popstation It says the data is corrupt.

Any help?

Well, PopStation just told you what was wrong; you .iso/.cso file is corrupted. Simply re-rip your CD and it should work. If it still doesn't work, then your CD itself may be too damaged to read.

Thanks for the reply but it turns out the card i bought used from gamestop was a fake.
