@misty I don't think Street Fighter on CD-ROM is quite as weird as it seems. Arcade games would routinely be extremely large by home console stds, since they weren't being mass-produced on the same scale. Buying those ROMs at the home release scale would have been prohibitively expensive.

Street Fighter in arcades was over 4 MB of ROMs. In 1988, it was inconceivable to do a home release of that size; only a handful of late SNES games in the mid-'90s were that big, after prices had come down.
