Ok, so I finally go an M3 simply. My first flash cart. I have been working on my ds homebrew title using an emulator so far. My game uses libfat, to read a few files. No writing, or directory traversing. To run it in the emulator, I patch it using dlditool FlashCartSRam driver. I assumed, that to run it on the M3, I would have to patch the .nds with the r4 driver. But when I copy my .nds to the m3, and try to launch it, the DS just freezes, at the loading game screen. What am I doing wrong here?
