Yes did find that one! They actually had a small arcade board selection too, with cheap CPS2 and Neo carts! Definitely the store to check out for bargains, as opposed to Super Potato which is really just an interesting looking tourist trap these days. The Surugaya in Osaka is good too, bought plenty from there in the past. I'm mostly done on collecting actual video games these days though sadly, prices are beyond insane for the titles I never got round to picking up "cos they were a bit pricey" years ago.
I've seen the arcade scene change in Osaka over the last 10 years from arcades like the Sega/Taito/Namco arcades in Namba having a decent mix of games like fighters, shmups, drivers etc to these days being mostly music games and Gundam Extreme Versus. Zarigani seems to have hoovered up all the old CRT cabs though and they have two locations absolutely rammed with goodies to play. The Nippombashi Taito Station still has a selection of Egret 2s with some nice games in tucked away in a corner upstairs tho!
Tis hard to beat Mikado and Hey though!
