According to profiler, the game runs through 44 different addresses
and EmuTOS several hundred, while the game is stuck.
I added to profiler a new mode which will show addresses/instructions
that were used during profiling, in the address order (i.e. not sorted
by instruction/cycle count). Results are attached, I hope they tell
what's wrong.
Btw. File is unmodified Hatari profiler output, I think it's pretty nice.
I'll add it to Hatari after I've added some extra configurability to
the 68kDisass.c code, to be able to set the disassembler options and
set/disable output columns from elsewhere in Hatari (temporarily) or
from the Hatari configuration file (temporarily). That's why I haven't
had yet time to look at the asm output more yet. :-)
