I'm about to skip across the pond to Dublin, Ireland for a little over a week, so I thought I might ask if anyone knows if there is much going on in the way of retro gaming over there. Are there any arcades, retro gaming stores, or people selling/trading games, etc.? What systems were/are big? Is there an abundance of Sega Master System systems and games? Any chance of hunting down a copy of Probotector or, dare I hope, Mr. Gimmick! for the PAL NES? Is there anything regional that is worth looking out for?

Thanks for the help.
