Oh didnt know there were conversions for these, need to look that info up.Personally, I'd just get one board and convert them. Save you some cash for sure.
We have free trade with Japan here, and most boards go through customs without any hassle (I havent had any problems yet).I spend 8-9 months to find a convertable namco system 2 pcb . If the prices of these games are on the prices related by Xtrasmiley & Rewrite, then these are awesome if can be imported . In anyrate, in romania we must pay on customs for items imported on higher prices.... i dont know in USA when you have to do this
