Atari Coldfire Project - Compatibility

Compatibility

There are different strategies for dealing with the differences in ColdFire and 68K instruction set and opcodes:

• FireTOS includes 68K emulation based on an illegal instruction exception handler and CF68KLib
• 68Kemu program (based on Musashi 68k emulator) can be used to run 68K programs with EmuTOS
• Most of the operating system and basic desktop software has been ported and built for ColdFire and rest is able to run with emulation
• Several commercial and shareware Atari SW packages have also either been ported to ColdFire or open sourced so that they could be ported to FireBee

FireBee FPGA doesn't yet provide DSP functionality which means that any Atari Falcon specific programs requiring DSP won't run. Many Falcon games and demos use it to play background music.
