Verified to work with EmuTOS too.

"Torus" works now fine.

Only "Susie" doesn't work, it's now stuck
executing these instructions:
  $00016690 : btst   #0,$fffffc00.w    50.00%
  $00016696 : beq.s  $16690            50.00%

Nicolas, any ideas what could be the problem?

Works fine for me with or without MMU.

(Using "--fast-boot on" and "--dsp none" for faster run-time.)

Can you retry?

Verified.

(Enraged doesn't work with EmuTOS.)

Verified.  It works with Hatari v2.2.0, but
doesn't work with Git version.

Laurent, would you have time to bisect which commit after 2.2.0 
regressed it?


Btw. This is pretty interesting case.  Screen
clearing before updates works properly only with
EmuTOS, whereas with EmuTOS the sound breaks
awfully when it renders text on screen.

Verified, but "Bound" (uses no DSP) seems to have
also regressed, I get now only a black screen.

Do you get same?

Verified.

I'll check these later on.
