If you import a US or JAP console, then you will need to use a 220v powersupply or a stepdown transformer.
Don't worry about video standards, if you have RGB SCART on your TV then you will have no problems and if you are using HD resolution, then you will also be fine.
There is also what is known as the ASIAN region consoles (its actually the same game region as Japan) but unlike the JAP 360, these come with a 220v power supply and component video cable (Jap uses D-Terminal cable and 110v).
http://www.play-asia...en-70-1909.htmlThe biggest issue with the JAP/ASIAN units is game support. Take Rockstars' Table Tennis for example. Take 2 do not have a local distributor for Asia/Japan (they use Capcom sometimes), so most of their games, including Table Tennis, are not available in the regions.
