I've been thinking about making a mame cabinet for a few years. Finally I got the motivation and put together one.
I had my old Pentium 4 3Ghz machine running windows XP. I installed MameUi32 and also Daphne so I can play the dragons lair roms.
I then wanted to see what I could do for the cabinet. Checking Ebay and Craigslist led me to a place an hour away (Grand Rapids Michigan) that had an old Golden Tee cabinet.
Once I got that I was able to put my computer in, then figure out how to do the X-arcade.
I'm not that good at wood working and stuff, and I also wanted the X-arcade to be removable in case someone wants me to bring my games with me to a party and this works out quite well.
All I think I want now is to find a button for the side of the Golden Tee (Dynamo Cabinet) that fits so I can use that to power my PC off and on. I have the power wired to a microswitch that I can just reach in through the missing slot for the bill validator and turn it on that way.
I was also happy I was able to make the coin slots work with mame!
I posted my progress on facebook.
