Lets go full crazy.
I'd have to dig for the photo again but it popped up in my feeds last week that someone had completely bypassed emulating 3DFX silicon in an FPGA and opted to instead graft a chip onto a new card with a bridge and a PCI Express slot. No, this is not the guy who made a Voodoo5 work on a PCIe to AGP bridge board.
In fact, I've seen a LOT of repro 3DFX cards coming out lately that are using original 3DFX chips, so either they have access to a lot of unused tray chips or they are already actively stealing them from original boards rather than starting over from scratch.
