The emulator that lets you play NES games in 3D has left early access on Steam

3dSen is an emulator that lets you play 2D NES games in 3D. Its programmers have to create a custom profile for it to work its magic on each game, which means there are currently 100 supported games, including Contra, Super Mario Bros, Batman, Castlevania, Bubble Bobble, and Gradius.
