I may be very late with this, but I couldn't find anything about this anywhere on the forum. Take a look at this: http://tinyurl.com/ypj9sn It seems like this patch makes it possible to use the Ewin GBA Loader (for their Ewin Expansion Pak) with its main competitor, the EZ 3 in 1! Currently I don't own either of them, but this still seems very interesting to me. Because when this is possible for the 3 in 1, why wouldn't it be for the M3 Perfect? So my question is: is it possible to make such a patch to use clean GBA roms from a Slot-1 flashcart on the M3 Perfect by doing this? I guess I wouldn't need an Ewin Expansion Pak anymore, right? If this is possible, how easy would it be to do this? Thanks in advance.
