This should be possible with any emulator for old school systems, like 286 with DOS, C64, Atari, etc. All you need is the ability in the game to "look left" and "look right" somehow, and tune the field of view for correct projection. If the game can't do that, then it might not be possible.

Also, the hacks in the blog post won't work as well for anything newer than DOS, like Windows games, since there is an OS in the way and writing over memory locations gets a lot harder. You would need to approach the problem differently.
