ok. the main reason why I posted just that previous code was the fact I
haven't access to that new one already (I deleted it after the prove it
didn't helped). but I know exactly how it looked:

previous code:

- Super() to get SV (init part)
- set trap vector (init part)
- do other inits and then loop in main loop:
- bsr.w movem_clear
- now follows the rest of code I post
- rts
- engine continues in SV...

I replaced with:

- Super() to get SV (init part)
- do other inits and then loop in main loop:
- Super() to get from SV
- now save a7
- bsr.w movem_clear
- do rest of code (movem loop)
- rts
- restore a7
- Super() to set SV

could it be?

I don't want to, I have to :) You know, writing/reading from/to dsp...
and please, don't tell me there are funcions for handling with DSP... I need
whole dsp (bootstrap code killed) with no overhead. And yes, this would be ideal, engine in userland ...

Ehm, not exactly "deeply", but I hope now are things a little bit clearer.
