here's the info i've gathered. Okay, i have a supercard minisd, 1 gig sandisk card, and superkey. They've been working fine. I just put pkmn mystery dungeon on my card last night. It didn't work the first time so I put it on again.. so there are two entries. I load up the second one, and you know how it starts loading, like x/1000kb or something and when it hits 1000 it loads. Well this had 30,000 KB which I noticed as odd to begin with. I'm playing the game, I reset about 5 times to try to get a starter, all of the sudden an error msg pops up "DS cart not read" or something and asked me to restart. I did. I powered on and off, and then it wouldn't read my DS. It went to the pick DS or GBA menu and if I picked GBA, it took me to the supercard menu but only showed my GBA Games. I wiggled around the Superkey, and blew in the slot. It worked again. I moved my DS the wrong way and all of the sudden, not reading error message. I power on and off again, and the warning screen comes up that is on the DS, but the letters are all 90% faded, so I can barely make it out. I reset again, same thing. I leave it for the night. I try again today. new version of the ROM. I tried it the first time.. 1110 kb, thats fine. I got dual black screens. I tried it again, 14000KB and dual white screens. WHAT THE HELL? I just tried super princess peach and it worked just fine as always. I don't think its my supercard. I mean, I was shaking hte DS around too to see if something disloged and gave me the error message. Nothing. If anyone knows what's up i'll be VERY happy. Thanks.
