We all know about the texture replacing function of the PPSSPP emulator that allows us to apply texture mods to games. But is there any way to do that on an actual PSP and/or on the PS Vita's Adrenaline?
my zill o'll translation project disagrees with your statement as i imported the game's ps2 version textures into the psp version and they run just fine with real hardware.
ofcourse, this sort of modding will always have to be done on a case-by-case basis.
