Playing MAME Games On A RGB Laser Projector

March 12, 2013 by Eric Evenchick 28 Comments

Vector based displays were used for arcade games in the ’70s and ’80s. A typical CRT uses raster graphics, which are displayed by deflecting a beam in a grid pattern onto a phosphor. A vector display deflects the beam in lines rather than a full grid, drawing only the needed vectors. Perhaps the best known vector game is the original Asteroids.

[Jeremy] built up a RGB laser projector, and wanted to run some classic arcade titles on it. He started off by using the XMAME emulator, but had to modify it to communicate with the laser and reduce flicker on the display.

To control the laser, a modified version of OpenLase was used. This had to be enhanced to support RGB color. The modified sources for both the MAME emulator and OpenLase are available on Github.

[Jeremy]’s friend, [Steve], even got a vector based game that he wrote working on the system. “World War vi” is a shoot-em-up battle about the vi and emacs text editors.

The results of the build are shown in a series of videos after the break.

Hackit: Modern Arcade Cabinets?

August 20, 2008 by Eliot 39 Comments

We’ve been contemplating getting into MAME arcade cabinet building. It was sparked by someone dropping off a Street Fighter II machine at our office. Many people have been seeking to build the perfect arcade cabinet clone, but looking over this old dusty cabinet we realized that retro isn’t really what we want. We want an arcade cabinet with a modern aesthetic.

Retro Thing recently posted [Martijn Koch]’s Retro Space. The cabinet takes design cues from old cabinets, but uses modern technology like a 24″ LCD. It does feature classic controls though. Wandering through arcades today, most of the machines appear to be DDR style or vehicle sims. No one is building modern gaming machines.

We’re still in the planning stages of this build. We’d definitely use classic controls and combine it with an LCD 24″ or larger. The brain would probably be a Playstation 3. We could run any emulator we want on the Linux side and also play modern PS3 games. How it will look is still up in the air. We’re leaning towards building a standup 4 player brawler machine for playing games like Teenage Mutant Ninja Turtles, X-Men, and The Simpsons.

Have any of you built a MAME machine before? How would you build an arcade machine with a modern aesthetic?
