Looks like a good workaround for PPSSPP, good find!. As for the PSP I'll have to try if there is no performance impact (though we all know impatient fans would be playing anyway ^^). Still, this is only for the merged, untranslated ISO. Since we have to edit videos as part of the translation project, the final CSO might still over 2GB, (little) time will tell.
