I purchased a Japanese Virtual Boy and will use it in USA. I want to purchase a power adapter for it and want to make sure I don’t use the wrong adapter and cause any problems.

Can someone help me understand what I should be purchasing?

Is there a difference between the USA and Japanese power taps? Which should I get?

Which AC adapter do I need to connect to the power tap? I’ve seen that in USA you can use a SNES adapter, but is that going to be the case with the Japanese Virtual Boy? I’ve also seen reference to having to use a genesis adapter or something too but haven’t found a clear answer.

Any help that can be provided would be greatly appreciated!

What you want mate is a US tap and the US snes a/c adapter. The Japanese tap has a different power adapter connection.
Hope this helps.

Ah.. so the system itself is the same in Japan and USA, just the tap is different?

Yes that is correct, they both run on 9vdc hence the 6 AA batteries. Its just the taps that are different.
