When I upgraded by Supercard SD (regular SD, not lite, etc. -- the original purple one) to the 1.7 firmware everything started crashing. Games randomly just lock up, usually the music keeps playing but everything else freezes. Sometimes I can't even get that far, I get an error saying that the SC can't find the SD card, "Please turn off GBA". Occasionally I can't actually get it to load at all and I have to give up. Sometimes it would go 20 minutes before freezing, sometimes it would freeze immediately, like while the logos in the game are displaying at the beginning. Didn't seem to matter which game either -- Children of Mana seemed worse than others, maybe, but NSMB, Metroid Hunters, and Mario v. DK 2 all crashed too.Tried re-patching with and without DMA for all ROMs, with and without Trim, etc., nothing worked. Tried formatting the SD card, no help. I only have one SD card so I can't try a different one. So I just downgraded to the 1.63 firmware and 2.56 SC software and re-patched all of the ROMs I had on the card, and everything seems fine. Anybody else run into this? I tried searching for similar posts but couldn't get the search engine to return anything (I mean ANYTHING -- "Supercard freeze", "Supercard crash", etc. all return no results at all).
