Doom has been ported to every platform under the sun.

These days I’m more interested in the non-direct Doom ports that exist. Such at Doom 64 on the Nintendo 64, which introduces new levels, artwork, music, sound effects… so a whole new game really

Another interesting port was the Playstation 1 version.

Fabien Sanglard has written a fantastic in-depth technical article on this very subject

Funny story on Playstation development: Aaron and I started out with a different engine architecture that rendered the world with triangles, since they were fully hardware accelerated. That worked great on the N64, which had subpixel accurate, perspective correct rendering (that SGI influence), but Playstation had integer coordinate, affine texture mapping, and the big wall and floor triangles looked HORRIBLE.

This lead to the dev team taking quite a raw metal approach, rather than taking advantages of any higher level Playstation hardware features.

The end result is something that looks just like Doom on the PC, rather than most 3D PS1 games which have a distinctive warping and wobble of their textures.

One key difference in this version is the awesome new original sound track from Aubrey Hodges which gives the game more of a horror survival vibe.
