I just got through playing a psx game no more than a week ago and now all of a sudden its not working i was just wondering why if anyone knows further about this problem plz let me know the psp has never frozen on me im running 3.40oe A i was playing vandal hearts on it and now when i try to load the game again as with every other psx eboot it just stays at the screen with the wave and nothing else i can turn my volume bar up and down and dim the light but its not loading it

ur gonna have to be more specific (ie any messages, freezing of psp) i suggest maybe upgrading ur firmware?

Have you mess the "recovery" settings before these problems occur? Maybe you can try this:

Check all your settings, in Recovery mode.(hold R as you turn on your psp)

Recovery Mode > Configuration
Use No-UMD - DISABLED (Remember to put a UMD in the drive)

Recovery Mode > Advanced > Advanced Configuration
Plain Module in UMD/ISO - ENABLED
Execute BOOT.BIN in UMD/ISO - DISABLED
Use isofs driver also in UMD-inserted mode - DISABLED

try your PSX and ISO games again.

You could just try reflashing 3.40, or you can wait for team AOP for their new CFW, then try that.
