@MEGNEKOMARU whenever you're done you need to activate the load textures setting and it should change everything, usually the textures are dumped as png files with opacity at 50% so you gotta take those criteria on mind
@MEGNEKOMARU well you need any pop'n game on ps2 and pcsx2, in settings there's a setting called dump textures (it'll give you whatever textures are loaded in and it'll create two folders, the replacement folder is the one where you can put the modified ones)
