well, for the big percentage of the games out, saves r universal. this mean that u can use a jap save whit the usa rom. like castlevania gba games: i began to play the jap aria of sorrow and i use the same save whit the european one. neuway, i'm happy of this release but not completely: basically is the same for me to play a game in english or in italian language - maybe it's me. oh, another thing: i never used the patched fft (U) - i just patched it whit fav8, maybe this release doesn't need it or maybe the same patch works whit it too, i have to check it out. i suggest to try it and to post infos about it.
regards,
