What is your thoughts on FPGA arcade board replacements? For those who don't know a FPGA is a special chip that can be programed to actually become other chips so it can emulate hardware in hardware which can come close to a perfect re-implementation or replacement if done right. Unlike MAME you can make the chip run at the same speed and act and load the ROM in the same way and have the same exact bugs and you can update the outputs to more modern outputs like Displayport, HDMI or just regular VGA. There are current projects that have re-implemented some games and there are even replacement boards on the market. I know there is a Williams multi FPGA board and a Berzerk FPGA. There also is the MiST FPGA project that is implementing arcade chipsets with some that are Works In Progress. What are your thoughts on this? Is this okay to preserve faulty boards like Berzerk that may not survive much longer. Which boards or games do you think are in need of an FPGA implementation? What are your thoughts on this in general?
