Short version: R4DS freezes on "Loading..." screen. Is this likely a bad R4DS, or a bad microSD card? Longer version: So, I ordered an R4DS with a 1GB C01G Japanese Kingston from dealextreme.com about two weeks ago and just received it two days ago. Formatted the SD card in FAT32, put the English v1.10 kernel in the root, and put a few roms in the root as well (all done using the included silver USB microSD reader, which I'm lead to believe is safe). Started off playing Ouendan - worked fine until a few stages in it froze. Tried again - froze at the same spot. So, I downloaded a different dump of the ROM, and was able to get past that area and couple others but froze yet again at another area. So, I moved on to testing another ROM - Puyo Pop Fever - which worked until a few minutes in where the screen garbled up and froze. Power-cycled NDS, and it froze on the "Loading..." screen. So, my next thought was to reformat the microSD card and try out the v1.8 firmware that came on disc with the R4 - did that, and tried it out - first time, froze on "Loading..." screen again. Tried it again, and it actually booted to the R4 menu, but froze on that. So, obviously, something's bad here, but my question is, does it sound more like a bad microSD card, or a bad R4DS? Naturally, I don't want to send back the R4 only to find that wasn't the issue, or vice-versa, so any help is appreciated!
