Retro enthusiast injects Snake game into vintage S3 graphics card VBIOS — enjoy some serpentum fun while your old PC boots

Bits und Bolts patched an S3 ViRGE DX graphics card VBIOS to embed the tiny Snake 512 game.

The mod adds a boot-time prompt, custom splash screen, and lets users play or skip the game before startup continues.

He fixed the checksum and tuned the colors so the game works cleanly inside firmware.

The project is a playful but practical example of VBIOS reverse engineering and low-level retro hardware hacking.
