Functional, but not presentable
In a previous post, I went over making your MAME controller functional using an encoder from Groovy Game Gear. This setup wasn’t quite finished though, as it had no back cover, the USB cord wasn’t properly secured, and the outside was simply bare wood. Hopefully this post can show you how to turn your project into something that will not only function, but also look presentable.
A fourth side was installed
The first thing needed was to put a back cover on the box. I had built a cornhole set using 1/2 inch plywood, so while at Home Depot, I had a strip cut to the height of the box (around 3 1/2 inches). Cutting the long side to length of the box (around 23 3/4 inches), I had a piece that could be simply screwed on and taken off if maintenance was needed. For these #8 wood screws, I used a 1/8 inch pilot bit to drill through the cover and the plywood it would screw into. I then used Read more »
Ripping out the wireless encoder
After a marginally successful attempt at building a “wireless MAME” device using an old keyboard, I decided it was time to bite the bullet and simply buy an encoder. Although the original setup did work as a wireless controller for very simple games like Pacman and Galaga, any more than 6 buttons (including four for the joystick) seemed to be beyond the capabilities of my controller (at least how I had it set up).
Finally finished and usable with an encoder
A quick search for MAME encoder reveals quite a few sources of encoders to substitute for your hacked-up keyboard. I finally settled on “Groovy Game Gear’s” GP-Wiz40 encoder because you could buy it prewired for your buttons with spade connectors (no solder required). Also, it has rotary encoder support which may be useful at some point in the future. I bought wiring for up to 30 switches Read more »
Hopefully you found the discussion about the mechanical design of my MAME setup informative, but the thing that – for better or worse – sets this apart from most of the others on the internet is the fact that it uses a wireless keyboard for control. One could probably use a wireless game controller (or possibly two) with similar or better results.
