Psp playing isos with delay issues.

I have system version 4.01 m33-2 and have some questioms. When I am playing games like final fantasy crisis core, final fantasy tactics or jeanne d'arc, the cinema scenes lag bad but the game play is just fine. But when I play games like star ocean 2 or valkyria chronicles 2 the cut scenes work fine. Do I need to upgrade software or are the games just slow. Using iso if it wasn't obvious. Any help would be greatly appreciated.

your firmware is very old, better update it to 5.50 or anything similar. i had no problems with jeanne d'arc on prometheus 3.

Update your current firmware, by following the respective section from this guide.
The latest CFW for M33 is 5.00m33-6(with Prom-3).

and did you play those games using UMD? If yes, dump the game to your memory stick.
If not, uncompress your games to ISO, if it were in CSO.

i think jeanne d'arc was .cso, how do I uncompress?

Either use UMDGen or PSP ISO Compressor.
Both are easy to use, only save the file as an ISO(Uncompressed), or CSO(Compressed).

thanks, as soon as I uncompressed it, it worked like a champ. No need to upgrade software now, good news cause I fried my Pandora battery haha.

testing

It could be your Memory Stick Pro Duo. DO you know any of the specs of it like class or at least read/write rates?
Should be listed wither on the box or web site.
