ROMs are not included. In order to use this arcade, you need to provide the
correct ROMs.

To simplify the process .mra files are provided in the releases folder, that
specifies the required ROMs with checksums. The ROMs .zip filename refers to the
corresponding file of the M.A.M.E. project.

Please refer to https://github.com/MiSTer-devel/Main_MiSTer/wiki/Arcade-Roms for

Note for Nova 2001 (From Mame)

- nova2001 is very sensitive to coin inputs, if the coin isn't held down long
  enough, or is held down too long the game will reset, likewise if coins are
  inserted too quickly. This only happens in nova2001 and not in nova2001u.
  (the nova2001h set seems to be an unofficial fix for this issue, presumably
   it's so sensitive it would reset sometimes in the original cabinet?)
- nova2001h MRA was added to address the original cabinet issue.
