MAME, an acronym that stands for Multiple Arcade Machine Emulator, is an emulator designed to reproduce older arcade system hardware via software on a modern personal computer.

Controls

The Williams Defender cabinet shared the "base cabinet" with many other games like Joust and Sinistar. This fact makes it very easy to make multiple control decks. The control decks dimensions are 23 1/2 inches by 8 inches made of 3/4 plywood.

We have a few leftover parts from the last MAME project, also ordered a set of buttons and joysticks form Ebay seller TwistedQuarter for $29.99 plus $10 shipping as a donation.

~~Danny is currently running a custom firmware on an Arduino Uno and checking the results of that.~~ Interface was too laggy

Custom Electronics for the Controls

A custom board was fabricated for controlling the buttons and joysticks V-USB MAMEPanel was ported to work for the Atmel atmega644p micro controller. The hardware currently emulates 2 joysticks with 8 buttons each and a keyboard hid device. MAMEPanel is expandable to 3 joysticks and a mouse input is also possible. Hardware has only been tested with windows built in tool for testing joysticks, real world performance is still to be determined. It should be fine since it is based on a working and tested design. Below is the current keymap and schematic.
