You may have seen the 2-D Flash version of Portal, but have you seen the Atari version?
This “demake” — the art of taking a current game and creating a retro version — not only looks like it was made for the classic console, it actually runs by using an Atari 2600 emulator. Technically, that means Super 3D Portals 6 could work on an actual 2600 cartridge.
The project was one of the entries in the Independent Gaming Source’s “Demakes” contest. It uses a two-joystick control scheme, so you can shoot both red and blue portals to solve the simple puzzles.
The flash version of Portal was so popular it turned into a free map pack for the PC version of Valve’s spacetime-bending puzzle game. Could Valve bestow its official-unofficial blessing on this version, too?
