From the project
Classic 1980s arcade video game implemented in an FPGA using Verilog
Classic 1980s arcade video game implemented in an FPGA using Verilog, using some custom video, sound, and controls interfacing hardware.
This project is stable. It has served the Church of Robotron well during the 2019 Crowd Supply Teardown conference and the 2019 Portland Mini Maker Faire.
Lattice LFE5UM5G-85F-EVN FPGA evaluation board: This is an economical way to get the largest ECP5 FPGA Lattice makes. Williams Robotron: 2084 ROM binary files: These files are often used with MAME, the arcade emulator. CPU board ROM files are named "robotron.sb?", where "?" is "1" through "9" and "a"…
