So far my Supercard SD experience has been nearly flawless. Here's the quick summary- - I ordered from RealHotStuff. - My SCSD has a red circuit board. - I'm using the new Supercard OS "1229" - My MicroSD is a 1GB SanDisk Ultra II (the fast kind): http://www.sandisk.com/Products/Item(1874)...icroSD_1GB.aspx - I've formatted my MicroSD as FAT16 with 64k clusters. (haven't tried formatting any other way) - I am not using clean roms. My roms were clean, then I patched them with the official Supercard software, v2.58. I did this to enable direct saving as well as the quick reboot key combination. When I run the SD speed test, I'm told that my MicroSD is really slow and that on a scale of 1 to 32, *5* is the speed I should use. This is TOTALLY INCORRECT and is way too slow. I'm able to set my card speed to "4X" (whatever that is on the 1-32 sale, I have no idea) and so far it has worked flawlessly. The intro video for Castlevania: Dawn of Sorrow is flawless and runs at FULL SPEED. The intro video for Castlevania: Portrait of Ruin is flawless and runs at FULL SPEED. I've played this game for about 30 minutes so far and I've hit the start and select buttons non-stop for about 30 seconds. I didn't experience a single crash or freeze. I just got my Supercard today and so far so good. I'm not saying that Castlevania won't crash in the future, or that other games won't have problems, but from what I've seen today I really don't have anything to complain about.
