Voodoo Reborn: 3DFX GPU Recreated in FPGA

Francisco Ayala Le Brun has recreated the 3DFX Voodoo 1 GPU in SpinalHDL for FPGAs, detailing the fixed-function hardware architecture and the timing/bug challenges of mapping a classic GPU onto modern programmable logic, with a GitHub repository for curious readers; the piece nods to Nvidia’s late-90s acquisition of 3DFX and notes the option of upgrading real Voodoo memory for those who own original hardware.
