If you are really aa oldschool 2D gamer you have to own a PSX, Saturn and of course the PC-Engine DUO, maybe a Dreamcast too. Then you can play ALL the classics like R-Type, Raiden, Gradius, Parodius, Radiant Silvergun, Thunderforce etc. on real media.
This VC stuff sucks, the graphics are scaled/interpolated for higher next gen resolutions. Looks awful.
