When you google Mediamatic & Arcade, you'll find an announcement that they were looking for a student who should organize this event as a 24 hrs internship a week. And asking around 2 weeks in advance for arcade cabs to lend. That's a bit...I dont know. Chaotic?
Last September I was at a comicfestival and on the second floor, there was a seperate section with Japanese comic and they had a SNES, Playstation, Sega Megadrive, an Arcade karaoke machine and some sort of Japanese slam the mole-arcademachine. Maybe venues like that are an option to show your cab. Downside is, that there are a lot of kids...
