I took some time to listen to some of the soundtracks in Rage Burst and they are awesome, especially the ending theme. It would be possible, if only the files aren't too encrypted. It's hard enough as it is modding a PSP rom so let's just stay on translating the game.I asked the question because I had a conversation about how great are the new musics in Rage Burst and the other reason is I saw people changing character model in Dissidia 012 and overhaul of Final Fantasy Tactics - War of the Lions
BTW, off topic: Now that Namco has announced God Eater Resurrection this fall 2015 makes it a good reason for me to buy a vita. Dunno which system it will come out though.
