TODO:
- atamanot: needs a trojan, in order to understand how the protection really works.
- colors (missing PROM(s) ?)
- samples (at least two of unused ROMs contains samples (unkn. format , ADPCM ?)
- samples (at least two of unused ROMs contains samples (unkn. format, ADPCM ?)
- dips (one is tested in game (difficulty related?), another 2 are tested at start)
Unknown reads/writes:
- AY i/o ports (writes)
- mem $c000, $c001 = protection device ? if tests fails, game crashes (problems with stack - skipped code with "pop af")
- i/o port $8 = data read used for $e command arg for one of AY chips (volume? - could be a sample player (based on volume changes?)
