I am running EOS SP2 on my Sandisk 8Gig SDHC with a Supercard onei, It was running just fine till I added my old game list from my M3 Real. After I did that, every time I clicked on my NDS file it froze. I sat there for a good 10 minutes thinking maybe the game list is too large, so I deleted some and tried again, it still froze, so I deleted more, still froze, deleted the whole contents of the NDS folder, froze. So I reformatted it and it worked, till I ran a ROM, then it froze after that. So I used the old Supercard firmware which worked, then used YSmenu and it worked fine there. So it's only EOS that is freezing.
