Re: [hatari-devel] DSP for Previous

[Andreas Grabher <andreas.grabher@xxxxxxxxxxxx>]

There is a little part missing in the SSI part. I did not re-implement it, because i had no need for it and no way to test it. I just commented out the old code. The commented code is in dsp_cpu.c, line 1137 and dsp_core.c, line 335 and 434. It needs to be adapted to the new interrupting routine.

I can help to fix that one. It should be easy.
