I saw TGOD seems to request RoboSport (MS-DOS version only).

But RoboSport hadn't been released as MS-DOS version.

I also reported the fact on MobyGames.

MobyGames removed about MS-DOS version from its Data Base a few years ago.

I have a lot of games from Maxis, but there is no MS-DOS version of RoboSport on MAXIS's Catalog or any card form package.

(I also checked about RoboSport on another package by Maxis.)

So this version of Robosport should be deleted from request, because no MS-DOS version of it hadn't been released.
