I bought a replacement R4DS for the one I lost. I didn't check the forums before I did, and after the first week of using it I read the forums only to see that there will no longer be software updates for this card and it was non returnable. (If this has changed please let me know). I used it for a month and then every game I play will freeze after about half hour. This happens with every game, but there are rare times when this doesn't happen. Is there a certain hardware problem or bug with the R4DS that this is a known issue with? I have been considering the CyclosDS because it's been very annoying just cutting my games off especially if I didn't just save. I really liked my R4DS but if I bought a dud and there are no more software updates the replacement for this broken one will be the CyclosDS. Thanks!
