Review

AceKard GBAtemp Review

Excerpt: "The biggest problem with the AceKard is its proprietary file system, the AKFS. Because of this, you have to use a PC running Windows to use their client software that is currently very buggy and lacking in functionality. You can't create folders, or organise games. And there are limitations when deleting games, in that you can only write a game of equal size to that which you deleted back into that space."

(You can use the [AKAIO] firmware to get more features and less trouble)
