I wonder if someone knows a 680x0 emulator that isn't under the GPL license.
LGPL and BSD may be interesting.
Try looking at
FAME/C. It has recently been used to replace the original 68k emulation in UAE for the GP2x giving it a pretty decent speed boost and seems to have good compatibility.
It is, however, probably 68000 only (no 020 or later instructions, no FPU). Also the license is unclear from the source code, however the current maintainer Chui is a decent guy and active developer who might be willing to re-license.
He's active on the GP2x boards, so I'll drop him a PM.
