This week I started the process of adding a M.A.M.E. PC to my cocktail arcade cabinet. The PC is a 3.33GHz Celeron D with 2GB of RAM and a 250GB hard drive. Probably a little overboard for a MAME PC, but I wanted some room to grow if I need it. I also wanted to make sure I had adequate horsepower to play games like Street Fighter II and the Metal Slug series, which can be problematic on slower MAME machines. The whole PC was under $300, but I also had to buy an ArcadeVGA card and a J-PAC from Ultimarc so that I could interface the PC with my vintage-spec arcade cabinet.

I decided to use Windows XP as the OS. I considered both Linux and DOS, but XP ended up being the best fit for my needs. I also installed a VNC client, an FTP server, and a wi-fi card on the box so I can administer and configure the machine remotely. That way I don’t end up elbow deep in arcade guts every time I need to make a simple software change. The arcade screen looks great with MAME, but using XP with a 640×480 interlaced screen is a nightmare…that’s where VNC comes in handy.

Finally, to handle sound I got a little unconventional and decided to modify a small car amplifier and an ATX power supply to drive the four 4″ speakers in my arcade cab. Most MAME builders just modify an existing set of PC speakers, but I wanted to try something a little different. Modding the ATX supply to work with the car amp was a lot easier than I expected and my bench test with a pair of junk speakers and a CD player sounded great.

Right now all I need to do is install the amp and tidy up the wiring and I’m done. I’ll post some pictures of the guts when it’s finished.
