First off, I don't have a slot 1 M3 cart and I'm not looking to buy another slot 1 cart at this point. GBA ExpLoader used to support the M3 GBA Expansion, but then Rudolph stopped developing it. I think the M3 GBA expansion underwent some sort of hardware change at some point (similar to the revisions made to the EZ-Flash 3-in-1), so if I buy one now, will it still work with GBA ExpLoader? I know I could get a 3-in-1 (which would be supported directly by my cycloDS), but I don't need rumble and I'd like to have the full 32MB of RAM for homebrew. Edit: I'm talking about playing GBA games, not using GBA ExpLoader to set the cart to RAM expansion mode.
