I have a 68882 16 in my falcon with a 40 ready to fit when I get some desk space!
Can your FPU code be enabled on the 040 and 060?
If I do go near the FPU for this, I will be avoiding 881/2-only opcodes like a bad flu. The 040 and 060 should be happy.
However I don't think a BadMood-based Doom will be the ideal 040/060 Doom. It's really aimed at a base machine as much as possible, and this is why I'm on the fence a bit re: the FPU...
For an 060 especially, using the DSP in this way is a bit of a negative performance effect. A more classic port of the original code (PMDOOM?) is probably a much better choice.
