As some of you may know, Asian version PSP games are really just the Japanese game but with an extra English/Chinese instruction leaflet in the box. So essentially, the actual game is no different than the original Japanese game.
The odd thing is that the save games can only be used with the version of the game that they were created in, i.e. saved games created in an Asian version of the game can only work with the Asian version, US saved games can only work with the US version and EU saved games can only work with the EU version etc.
This probably isn't possible due to saved games being encrypted but... Is there any way to use saved files from Asian version of games with the original Japanese games or vice-versa? I've had a search in Google about it but no luck.
