At a local bowling alley I came across this game (
Vapor TRX). It had a yoke similar to the Star Wars yoke. According to KLOV, the game came out in 1998, which means that Atari (or someone else) would have built that control within the last five years. (It's also a fun game, but it hasn't been "MAMEed" yet.)
That got me thinking if they are still building similar controls like that and if they are selling them? My guess is that they build them from time to time (as needed for games like this), and then it's "shelved" for a time, but nothing is available to arcade shops or the general public.
Anyone else know anything more about this? My guess is we are still left with finding an old yoke on eBay, or building one yourself.
