Pretty much what I was sayingNot a disc, but the GameBoy version of Space Invaders contains the rom for the SNES version of the game, which can be used through the SGB.
Probably doesn't count for what you're asking, but there were also some games for the early CD consoles that had some content (though not the actual game) playable on PCs and CD players.
Really cool!There were hybrid Mac/Windows CDROMs back in the 90s and early 2000s:

I remember that with the C64 and C16 tapes now! Never ever saw a C16 tho!A huge number of ZX Spectrum games had the ZX Spectrum 48k version of the game on one side of the tape and the ZX Spectrum 128k version on the other side.
Seen a few PC games come with both Windows and Mac versions in the same box
I didn't even know they still made disc based games.Even today some games still get released for windows/Mac on the same disc. Football Manager is one that springs to mind
