Hi, Ok, firstly my setup: I have a DS w/ flashme & an old M3 SD card with a 1Gb Kingston SD card and a DS Lite w/ Super Key & an M3 Lite MicroSD with a 1Gb OEM (Toshiba) Micro-SD card I'm running v30 (SD Version) firmware and patcher for both of them. The problem: When I cross-reference the settings I am having to use against the ones on the m3wiki or against those of other users on the Gbatemp boards. The settings which are compatible with my card are a lot slower than those for everyone else. For example today I couldn't get Final Fantasy III (U) to load with anything more than Safe-Mode, No-Trim and no Force R/W. Any other combination of settings either caused 2 white screens (no force R/W) or caused the card to hang on the loading screen (Force R/W). I've also had a very similar experience with most of the other ROMs I have tried to patch recently including Bomberman Land Touch! (U) and Elite Beat Agents (U). If required I could probably provide a more detailed list of which games don't work on what settings. This problem is driving me a little nuts because the Software reset function would really help me out when I'm switching games or backing up a save after playing and not being able to Trim any roms is also getting to be a pain. I've checked the ROMs and they're fine, I've also tried repatching several times and reupdating the m3 firmware on both cards. I've also tried both Forcing R/W and not forcing R/W for most of the set-ups. Clearly this is something I'm doing wrong as it's happening on both my set ups. but i can't for the life of me figure out what it is.... If anyone can help me out I'll be your best friend forever or something.
