Brickseek is showing one store (30 miles away) with one... but I wouldn't want it just for that and would want to mod it to run other games.
I was looking at Reddit last night to see how easily it could be done, but couldn't find a ton of info for that particular cabinet.
Anyone here have experience with that?
I haven't modded that specific one, but the mod process tends to be nearly identical for every Arcade1Up. The only differences between them are:
1. different Arcade1Up models have different monitor models. Because of this, the specific LCD controller board (something like this -- its purpose is to allow you to use an HDMI cable) that you need will vary depending on which monitor your Arcade1Up comes with.
2. in the Simpsons case, they have a trackball on it. I'm not sure how that works.. I'd assume it's pretty much just an analog stick on a technical level, in which case you'd mod it the same way you'd mod the other players' buttons, but I could be wrong. If you don't want to use the trackball at all, then it's whatever, no need to worry about this part.
3. the number of zero-lag USB encoders you need, which depends on how many players the Arcade1Up supports (4 in the Simpsons case).
So, part-wise, you're looking at...
1. the LCD controller board. Don't order this until you have the Arcade1Up in hand, because you need to make sure you get the right version by looking at the monitor's serial number directly.
2. zero-lag USB encoders (example - this one comes with two of them). You need one for each player, and maybe one for the trackball, so that's 4 or 5.
3. (optional) new buttons. Arcade1Up's tends to be somewhat low quality, so most people replace them.
4. (optional) speakers, since the monitor's speakers aren't very good. And FWIW, I had trouble getting the monitor's speakers to work in my mod personally; installing a regular set of PC speakers via an aux cable was easier to get working.
5. a Raspberry Pi or PC to hook it up to
