I checked some the three things in compat list that were earlier getting
stack overflows:

* Reservoir Gods: Are you sitting comfortably?
  - Seems to get further before fails, no DSP overflow

* Toons: Yepyha
* Digital Chaos: Built-in Obsolescence
   - Still say "Dsp: Stack Overflow"


Didn't notice any regression in the other things I quickly checked.

Still for the release?


Btw. Thomas, I noticed that I can switch in the system dialog DSP on
(from off) without Hatari reseting the emulation.  Without reset it doesn't
work as expected...
