/*
  Appear to be Z80 based, some rom scramble?

  Maski Show has what appears to be a HDD image in 'WHX' (WinHex Backup) format - convert it to CHD
  Other games don't seem to have such images, missing.

  Roms are strange sizes, they appear to be cut at the end of the last block of data, some sets contain
  roms padded to normal sizes.
