Hi, I have: SuperCard DSOne v3 (SDHC) - I think the firmware is from 2009.05.23 A-Data 4GB Class 6 SDHC card - the speed setting in the DSOne's OS is set to (autodetected) 30 (I've tried with speeds set to 5 and 25 as well). DS Lite I've had the above 3 for about 1 year now. They've been working perfectly fine up until about 2 weeks ago. For the past ~2 weeks, my DS has been freezing up on me while playing (Suikoden Tierkreis US is what I'm playing at the moment). It'll play fine for about 5-10 minutes, but then I'll get the 1st freeze. After that it'll usually freeze before it gets to the game's intro screen or within 2 minutes (doesn't matter whether I do a soft or hard reboot). It'll start freezing up when I try to load other games too. However, it won't freeze when use Moonshell (both the OS as well as v2.0) to play media (dpgs). I've found that, once the game starts freezing, if I load a real-time save (after rebooting) of the game, I am able to play for several minutes before it freezes again. If I leave the off for several hours, I am able to play for 5-10 minutes before it starts freezing up again. Any idea what's wrong? I don't think it's Suikoden Tierkreis since I was playing it for several weeks before noticing this issue. Could it be the SD card? The DSOne? The DS? Could the SD or DSOne be overheating or overstressed? I'm able to play DPGs without a problem, but that may not be as intense on the SD and DSOne as playing games. I found a posting with something similar (http://gbatemp.net/index.php?showtopic=122273), but it didn't give a resolution. I'd appreciate any help on resolving this. Thanks.
