I find this release to work worse then previous one. For instance Sonolumineszenz demo doesn’t work anymore (exits after few seconds).
I can reproduce this. The demo dies to DSP stack overflow.
It seems to work better if I disable cycle exact emulation and prefetch.
Disabling cycle exact seemed enough.
I thought this was supposed to enhance compatibility? :)
It should be, but there seem to be some regressions from
state somewhere between 2.0 & 2.1.
NOTE: fragile DSP demos that rely on exact timings between
CPU & DSP instead of doing proper synchronization between them,
can break or start working with small changes in CPU/DSP timings.
This can include also changes that make some parts of the emulation
more accurate.
(Falcon emulation isn't yet really cycle exact, especially in
regards to CPU <-> DSP and CPU <-> FPU timings.)
