Hacking GBA ExpLoader cuts to a white screen after the GBA logo?

[badfingerboogie]

Hi guys, I know you've probably had a million topics like this, sorry to pester you with another but I can't find any help elsewhere.

Bought an M3 GBA expansion pack recently, but after (seemingly) setting everything up, I can't actually get anything to run past the 'Game Boy' startup screen.

My setup is as follows:

Slot-1: R4 DS (real)
Firmware: Wood R4 1.49 (or whatever the newest one is)
Slot-2: M3 GBA Expansion pack

I've tried both GBA ExpLoader 0.58a and the latest one, the 0.58b0_MX varient.

Still no joy - I get to the main screen on ExpLoader, choose to load whatever game via SRAM, it analyzes the rom, then writes to RAM, then begins the game. The GBA logo plays, as usual, then I just hit a white screen. This is the case with all games.

Am I doing something wrong? Or is this setup just not copacetic? May have to buy an EZ 3-in-1, I guess.

OK, scratch that, think I trashed the thing completely - not sure what I did exactly, but now whenever I load up ExpLoader it simply says '0 games', and I can't press anything. I've switched out different versions of it, different .ini files, deleted all the SRAM .savs that had been created, as well as the .sgn files, still nothing.
