Click on the game you wish to learn more about. So far, these are only available in Japanese so if you want to play them, you'll have to import the games. Unfortunately as far as I know, Japanese retailers can only sell their games within their own country only so you'll have to see if your local import store can get it for you.

You'll find my guides for the 2 GBA games, Metropolis Dakkan Sakusen and Jagan no Fuuin here. Do not send e-mails asking me for ROMs!
