Actually when this happens to me I have at least 20mb of free program Memory (All my applications are in my 128mb CF), and still had this problem. But I got it fix without Hard resetting my Cassiopeia. Suprise that Mameboy is not using GX.DLL, but I need it for the MAMECE3 and some other Jimmy Games. Reinstalling the GX.DLL Works for me.
