Well since I'm visiting Japan and I'm kind of a hardcore NES fan, I broke down and bought an original '83 Famicom. Games here are usually very cheap, typically between $1 and $5, so it's been cost effective so far. But, now on to the questions:

1. All of the familiar RF problems aside, my main question is about voltage. Will I need a volt converter for when I return to the states? I'd rather not destroy my investment by a power surge as soon as I plug it in.

2. I'd also like some recommendation of some Famicom games. I know my NES, but I'm a little more rusty on the JP side of things. Specifically I'd like to know about good games which haven't been released stateside and aren't very text-heavy or dependent (my favorites are usually platformers or shmups). I know some Japanese, but not enough to play Final Fantasy III. =)

Thanks for help!
