i remember reading that rudolph was asked to not support the m3 expansion pack. that is interesting to see that patched version, i didn't know about it. to clear this up, akaio only supports the flashadvance s1 gba card (because smiths owns one), and the 3in1 expansion packs. there is code for the ewin expansion packs but thats code left over from the bliss o/s. it has never been updated, debugged, checked, optimized, etc.
i understand how your feeling about spending the cash but a 3in1 is a great investment. might be something to consider and save up for slowly. a few bucks a month won't seem like much and in the end you have a new toy to play with.
cheers,
