The binary is from this package:

"taut_ii.prg" freezes right at start; after Sentry finishes
unpacking, resolution changes and screen becomes white.

If I do "return false" in cancache function, it still freezes,
so it's not related to cache.

However, if I use "--cpu-exact off", game starts fine.

I played them for a while, so this seems unlikely.


Btw.  I noticed few games in compatibility list which are still
marked "Doesn't work with WinUAE".  I'll check whether those
work now.  I've already checked few things which has similar
text with different wording and those worked now fine, so I'm
optimistic that your changes have fixed most of the remaining
ones too. :-)
