Format your SD card to FAT32 with 32kb cluster size, and set Mario Kart DS as donor ROM, if you haven't done that yet.EDIT 2: Got Boot9Strap running fine and am finishing up cleanup. The game seems to work and now it is at a "Loading..." screen with an unfilling progress bar. Ideas?
Also, TWLoader is not an emulator. (It's not called TWL-Emulator. ) It reboots into NTR/TWL mode to start bootstrap, which runs your selected ROM natively.
