GBA Roms on NDS With Passcard & M3 Help

Hi Guys
So i recently felt the urge to play some old GBA Favorites, but using roms with my NDS.
I'm using a Passcard (NDS slot) along with a M3 Mini SD (GBA Slot).

I got the roms, used the M3 Game manager along with the settings on the M3 Wiki page, just like i would with a NDS Rom.
After writing i booted the DS up and selected the GBA Game - Pokemon Fire Red (E) in this case - I waited at an unfamiliar loading screen patiently until it reached 100% and froze on a black screen.
Booting without the passcard inserted (just using the GBA menu) and loading the rom gave me a white screen :S

I tried all different writing setting combinations with the M3 Game manager,
I tried directly copying and pasting the rom onto the SD Card,
I tried trimming the rom,
I re-downloaded the rom just to be sure,

This is the first time I've tried running GBA roms on my setup. I've never had a problem with the NDS roms i can't handle myself.

I don't have a clue what the problem is...
Can anyone tell me what I'm doing wrong?

Thanks

Small update (but also a bump :-\)
I'm using a fat, older model DS.
Today I tried my setup on my friends red DS Lite. Exactly the same outcomes. (Well i didn't expect much -_-)
