I second that.
The falcon is a machine with a MMU, it should be enabled.
But maybe the timings in MMU mode are worse than in cycle exact or
We should be careful with that before enabling the MMU
IIRC without looking at the sources now, cpu is indeed less
cycle-accurate when MMU mode is set.
I guess for now MMU mode is more about running unix like OSes under
680x0 cpu where memory protection and all are needed, than about being
cycle accurate to run demos/games.
Maybe it could be disabled by default for falcon, I don't think many
games/demos are using it anyway, and TOS test for MMU can be bypassed

Almost all of the games & demos currently listed
in compatibility doc as needing MMU with WinUAE
CPU core, work also if:
- oldUAE CPU core is used instead, or
- CPU exact & compatible options are enabled
What enabling MMU for 030 does in regards to
WinUAE CPU core emulation accuracy?
