Full design files (editable schematic & PCB, PDF schematic, GERBER files, BOM, P&P, PCI bracket dxf file, FPGA bitstream and mcs file) are attached below. The FPGA code will be uploaded after I cleanup the code a bit. If you use another flash device, generate a new mcs file from the bitstream.

      1. I tested it in 86Box and with Voodoo Graphics (Obsidian+Amethyst) 12MB (2 TMUs) it won’t work (Quantum3D drivers) or have graphical bugs/glitches making it unplayable (other drivers) but with Voodoo Graphics 8MB (1 TMU) it works fine with no problems whatsoever. I wonder if it is the same with real hardware?
