I don't know if this has been covered before (sorry if it has).. But I've been thumbing through the forums searching for the answer.. Back in the days of plain old vanilla 1.50, I used UMD Emulator (with the little yellow happy face icon) to run ISO movies.
Since Devhook came out, I haven't been able to run that app, and now I'm using 3.10 OE-A' That doesn't seem to like the UMD Emulator app either.
Anybody running ISO movies on their PSP, what and how are you doing it?
I also have 1 JAP and 1 US psp, Although there are options to select Region Free emulation in the recovery menu, they still don't allow me to play umd movie discs on crossed units (ie. U.S. UMD on Japanese PSP).. Any ideas of comments on the subject, please post! Thanks
