You're definitely not going to see an ITG cabinet (upgrade or otherwise) at a R1 location. They have "legit" cabinets, so you can expect DDR or PiU, but nothing like a stepmania machine.
If you look at the OP of any of the other arcade threads, you can see the code used to show the game lists. And since you're the OP in this thread, you might simply be able to edit the post to show the game list instead.
So has anyone gone to this newly opened Round1 yet? Eugene is closer than Tukwila, WA for sure but still a journey (I'm in Portland) so I haven't been able to check it out yet. So I'm hoping someone could at least tell us what machines are there! I'm assuming the standard 2x IIDX cabs, 2x SDVX cabs, 1x DDR, and Gitadora setup and sometimes they'll have an old Pop'n machine. But it would be nice to know for sure and to see if they got an IIDX Lightning cab as they did in Tukwila R1.
Note: Credits cost different depending on what packages/bundles, and what level R1 membership you have. For 2017 prices as for an example, $5 is 20 credits ($0.25 per credit), but if you spend $30 you get 150 credits ($0.20 per credit). Then if you are an R1 Club Member you get about a dollar off on packages above $5. So if you buy the $30 package, 6.4 credits will be about $1.28 and $1.60 if you just buy $5 at a time.
Round 1 is definitely going to be your best bet. You could also check out this arcade search and see if you want to visit any of these arcades. The site doesn't show them as having Pump It Up machines, but there's a chance some of them do.
