I played Etrain Oddysay 1 with ACEKARD 2i (HWID:81) + AKAIO 1.6 RC2. I found that when I saved the game, there is random unsaved the last progress but load only previous progress of game. This problem look like be reduced when I copied new AKAIO firmware files to Micro SD Card (w/ or without format before). Is there anyone have the problem like me?
