 Crap XXX game.
 Three roms contains text "BY YACHIYO"

 Upper half of 7.bin = upper half of 8.bin = intentional or bad dump ?

 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 ?)
 - 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?)
 - i/o port $1a = 1 or 0, rarely accessed, related to crt  writes
