Final Fantasy I & II Remakes Confirmed For GBA
Thanks to 1UP for its story revealing Square Enix has announced a Game Boy Advance compilation of Final Fantasy I & II, due to debut in Japan this July. The article mentions: "That's the same pair of 8-bit RPGs that came to North America for the PlayStation as Final Fantasy Origins. However, the GBA remakes will feature a few new extras on top of the content from the original games", including new dungeons and substories - the remake also "seems to use the magic point system from later games in the series", and a U.S. release is likely but unconfirmed.
Actually the GBA doesn't feature version encoding.
You can play Japaneese games on a US game boy and vice versa.
Actually, the GBA has emulators (pogoshell) which you only need a flash cart and USB cable to transfer games over. I've been playing the NES version of FF1 on my Game Boy for quite a while. It's the only way I was able to get through some boring lecture classes. Google for Flash Advance for the cart, and Pogoshell for the OS (of sorts)
