I can't update the firmware, or add cheats. i use the supercard 2.66 for SD version patcher (which is the only one that works). I bought this more than a year ago here in manila...back then i didn't even know there were fakes. i hope the link i provided works and someone would be kind enough to help me out.
BTW, the black screen with the supercard logo is always at the bottom.
