Ok. So I've searched the forum with google, but couldn't find anything responding to my search queries. Maybe I'm just not thinking of the correct search queries, but I was hoping I could get something newer than a 2006 thread on this topic! I bought a Supercard DSone a couple of weeks ago, and had been using my brother's MicroSD card with it until I bought my own one. It's a 2gb regular MSD, and it worked like a dream. I was able to play Mario Adventure, DarkDaiz' romhack, on it perfectly, and I was really enjoying it. Bought myself an 8gb MicroSDHC a couple of days ago. It's great, and there's plenty of room on it. Except NesDS has stopped working flawlessly. It still plays most Roms, but freezes up when I try to save state, or load another rom. I've seen this problem mentioned along with MSDHCs before, but I couldn't find any fixes for it, and I'm desperate for a solution that doesn't involve swapping microSDs whenever I want to play a NES game. Besides this, it freezes up the moment I go to start playing Mario Adventure, so that's completely out. Which was sort of the attraction! Before anyone mentions it, the Supercard is supposed to autopatch all .nds files with a DLDI patch. But I didn't leave this to chance either, and tried patching it myself, and turning off the autopatch feature to see if that worked. Nothing. Subsidiary query.... For some reason, NDS_TGM loads on my SupercardDS1, but it's just a black screen. The problem was mentioned on the original website of the game, but there was no solution, and that was about six months ago. I know it works on my DS using an R4, so the problem seems specific to the SCDS1. Does anyone know of a solution or a workaround?
