doom on a 12mhz cpu ... well, forget it
maybe wolfenstein with agressive optimisations (like on megadrive) but only possible on neogeo cd

There's a version of Doom on the ZX Spectrum - uses a 3.5mhz Z80 as its CPU (Basically a slower version of the Neo Geo's sound processor)

This is NOT a Doom port, this is a remake or demake with extremely degraded graphics and 3D capabilities
it was remade from scratch with ZX spectrum limitation in mind, it's not a straight port of the original source code

I assumed the OP meant a version (rather than a direct port of source code) of Doom for the Neo Geo, like you had on the SNES, 32X or Jaguar, Playstation etc. Many of those suffered from compromises. E.g. no floors in SNES version, reduced window sizes, missing levels etc. The ZX Spectrum version of Doom is very impressive considering the limited hardware. If someone can do similar for the Neo Geo we would have a version of Doom to be proud of.

Wait a minute, does Neo-Geo really can`t to rotate sprites at real time?

No. It can't even zoom sprites, only shrink them down.[/quote]

Oh, noooooo! #facepalm#

Although 'Sprite Shrinking' is better because the image doesn't go blocky when you 'enlarge' it. Imagine how blocky the Art of Fighting games would look with sprite zooming. Instead you have perfect detail.

Hardware rotation of sprites would have been useful though
