Hackers Run Doom on Stock Neo Geo at 80x56, Undercutting “Impossible” Claims

Summary
Two hobbyist projects have produced functional Doom ports on stock Neo Geo hardware, challenging a recent claim that the console could not practically run the game.
Doom64KB renders through the Neo Geo’s fix layer—normally used for menus and HUDs—to create a proto frame buffer, yielding a smooth but highly compromised 28x32 image in 16 colors.
A second approach repurposes sprite memory as a frame buffer, lifting effective resolution to 80x56 with 4x4-pixel blocks, though the gain comes with a clear frame-rate hit.
The results remain far below what a marketable 1990s port would have required, but they show how determined coders can stretch legacy hardware once labeled impossible.
