I run it on a $50 Pentium and it seems to work fine. As was noted LB is undergoing development and they have revamped it at least once for speed improvements of the interface. I wanted a game front end on that computer and I started out with Hyperspin. That was some of the most convoluted software I have ever worked with and after spending hours trying to get it to work I found Launchbox. Launchbox was up and running in minutes and seems much easier to configure and customize. I haven’t put it into full Bigbox mode yet but I have played with it and it seems to run fine, no slowdowns.

Personally I prefer a minimalist interface that simply shows the games then lets you select one and launch it. So I don’t have the full-on interface that has all the fan art, music, game play videos, etc. Also I only load it with a somewhat curated list of games so that might make a speed difference. I think I have about 300 total games in there right now. Some people like to load the entire packs with thousands of games, but I’d rather keep it simpler and just show stuff I want to play.

I like Launchbox for a front end. I'm pretty sure I read somewhere on their site that they are working on something improved for pinball. That's the only thing I haven't gotten running clean yet. I haven't put too much effort into though, been distracted playing other stuff. Like, Doom.

Same here, but I am still working through the controller issue. How are you handling that?

I have found that some arcade games play pretty well with a wireless Xbox 360 controller. A few examples: Asteroids, Space Invaders, Galaga. However, others don't work well at all with it. A few examples, PacMan or anything similar, forget it - needs a real joystick, Centipede and others need a real trackball, and Breakout and others need a real spinner. There is no ready-made portable arcade control panel for connecting to TV/Couch setup that I know of, so I am trying to figure out how to make one.

So the Ultrastick will work well with PacMan when set for 4-way? This is one thing I have wondered, not having one to test. I've been thinking about getting one of these. That should be good for everything 4-way and 2-way. Unfortunately Qbert and Zaxxon won't work out unless there is a way to rotate it 45 deg.

Check out the leaf switches, basically the same as on a pinball machine.
