Hmm. So, I purchased an R4 SDHC RTS Lite card not too long ago. It worked fine and all, until I tried updating it for Pokemon Conquest (since it's not out in Europe). Anyway, I followed the multi card update and did everything it said, such as something with a TTMenu. It's always best to backup your microSD to a folder called Backup on your PC before upgrading to a new firmware version. That was literally on the 'How to install.txt' file. Anyway, I loaded the TTMenu.nds file and my screen went blank and it kept loading for a long time and did nothing more. So I restarted my DS and suddenly it couldn't find my R4 card..... Yeah, I've tried to format my SD card and stuff like that, load the original firmware on it, however it still displays nothing, anyone know how to fix it? I'm terribly lost and it's already happened before to my other R4 Dual-Core card. Sorry for the trouble!
