"WAVENet was never publicly released. There were tests in Chicago and the San Francisco area on UMK3 and Rush 2049. It ran over a T1 line that was directly connected back to Midway HQ in Chicago.
It's highly unlikely any of those test games were ever sold to the public after WAVENet was dismantled so it's unlikely the ROMs are out there. You would be better off playing vanilla MK3 via a MAME networking kit like Kaillera."
" Yes. That was one of the reasons WAVENet didn't really take off. This was long before the age of cablemodems and DSL. T1 was the only guaranteed way to get broadband into an arcade.
Times have changed, but it still is kind of hard to get net service in a lot of places. The internet jukeboxes are starting to drive the adoptance of broadband, which is a good sign."
"I was working on the pinball side at the time (although we had a WAVEnet unit to play with in our offices).
If I recall correctly, the game didn't use much of the T1. Midway picked up the cost of the line during the tests. You can get a T1 installed anywhere you want, as long as you pay what Ameritech wants. It's just a dedicated copper pair that's specially installed at the telco."
