Hackers quickly prove that Neo Geo Doom ports are not "impossible"
Summary
Two hacker projects have made progress in running the game Doom on the old Neo Geo game console, which was previously thought impossible due to its hardware limits. These projects use creative methods to display Doom's graphics, although the visuals have big compromises.Key Facts
- Doom was considered impossible to run on Neo Geo because it uses sprites and lacks a normal frame buffer (a way to quickly redraw the screen).
- The Doom64KB project uses the console’s fix layer (normally for menus) to create a simple frame buffer for Doom graphics.
- Doom64KB shows the game in low resolution with only 16 colors and large tile blocks.
- Another method called Doom-NG uses a technique to render walls as vertical strips of sprites, simulating the 3D view of Doom.
- Doom-NG creates a recognizable but striped and blocky version of Doom that runs smoothly on Neo Geo hardware.
- Both projects still miss features like enemy behavior, music, and weapon choices.
- These early efforts show how skilled coders can push old hardware beyond expected limits.
- Further improvements could make the game run better or look smoother, especially with hardware modifications.
