Why is a Neo Geo port of Doom impossible?

Neo Wolfenstein

Even those limitations may hold back the Neo Geo Destruction port, the system can handle simple FPS like Wolfenstein 3D. Modern Vintage Gamer put together a simple Neo Geo raycasting display for video that matches 90-degree walls, floors, and ceilings.

The “walls” in this raycasting display are 4-pixel-wide sprites enhanced by Neo Geo hardware.

The raycaster works by sending light from the player’s position to determine the distance to the first wall that the player can see on the line. The data determines the height and color of each set of 80 4-pixel-wide sprites arranged horizontally on the display, which act as wall pieces. Since Neo Geo’s scaling hardware can efficiently stretch their sprites vertically without being too high, the raycasting data can quickly turn into a chunky simulation of the first person view.

Neo Geo’s simple, default MVG raycaster currently runs at eight frames per second through an emulation with nothing. Wolfenstein 3Denemies or game ideas. And raycasting would have been incomplete Destruction things like raised platforms, stairs, elevators, walls and ceilings, etc.

For all these reasons, MVG believes in the only way to get it Destruction run on the Neo Geo and carry additional components in the cartridge, such as the Super FX2 chip that is controlled. limited SNES port of the game. Failing that kind of power, he doubts the system will last doom-free future previews.

“I don’t want to say it’s impossible because as soon as you say something is impossible, the gauntlet has been thrown down,” added MVG.
