Hi,

I added the DSP code from Hatari v1.8.0. It was easy to make it compile. But then i ran into an early problem:
The 56001 has 4 operating modes:

Has anyone some insight in how the other modes could be implemented? At first look the differences between the modes seem to be mostly related to DSP reset.

IIRC the modes affect two things - the reset 'delay' (16 cycles vs 'lots') and the address of external memory to bootstrap from. However, I haven't used any of that so there may be further complications :)
