  TODO

  Add more Famiclone roms here, there should be plenty more dumps of VTxx
  based systems floating about.

  Make sure that none of the unenhanced sets were actually sold as cartridges
  instead, there is a lack of information for some of the older dumps and
  still some dumps in nes.xml that might belong here.

  NON-bugs (same happens on real hardware)

  Pause screen has corrupt GFX on enhanced version of Octopus
