As @Badwolf Pointed out, there is no actual OS accessed during the game
I should say that I'm not asserting there are *no* OS accesses in the game. I just haven't come across any significant ones.
Keyboard, mouse and joystick perhaps?
Anyway, fairly few in the scheme of things, I'd say.
The MAPROM slowdown is indeed an odd one. I would have thought MMU overhead shouldn't exist (MMU already is active for shadow register mapping AFAIK), but I also don't know what I'm talking about.
I've tried a couple of times to follow how the MMU works and Anders' code and haven't yet succeeded!
