Both Madusa as Milan are involved at the Atari Coldfire Project. And both bought licences for their computers mid of the 90ies. The contracts were done with the original Atari Inc. before it was sold to JTS in 1996. So we have the original sources, not disassembled code.
While you are here, can I ask you a question about the Firebee?
Specifically, how do you handle running old 68k binaries with no source available that use instructions that exist on both the Coldfire and 68k CPUs, but behave differently on each?
