Hacking my homebrew won't launch on M3 Simply

[beefstew]

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?

All I can tell you is that you're doing it right (R4 driver, etc.) -
I haven't personally used the libfat in projects so I can't help you more with that.
If I were you I'd look at the code and try to find specifically what makes the loading process fail.
Comment some lines, one by one, try again etc.

edit: anyhow, you know this isn't the best place to ask right?
for homebrew and development in general I recommend http://gbadev.org (forums) and if you want a simple lib use PAlib ( http://palib.info/wiki/ )
