Raiders (Century Electronics 1981)
==================================



ROMSET:

* CVS\cvs_raiders.zip  --> Renamed to raiders.zip

* The game has the same problems with sound like Superbike (CVS)

* Graphics and gamplay ok

* Most Wanted says:  "Raiders" (1981?) -- we have a couple of dumps of this
                      but we're not sure that any of them are complete
