No Playable Games

[James M Knock]

The package installs and shows four games with names I do not recognize. None of the games play.
A message comes up:
"No games found. Please check the rompath specified in the mame.ini file.

If this is your first time using MAME, please see the config.txt file in the docs
directory for information on configuring MAME."
