Hi, i am after some knowledge please. Will the Jap tap adaptor work with a USA Virtual Boy?

Any help would be appreciated.

Yes. The controllers are exactly the same, so the port where the battery box/tap connects is also the same. The only difference is the barrel-jack (on the tap) into which the AC adapter itself is plugged.

The U.S. tap uses the proprietary SNES adapter while the Japanese one (I think) uses a standard barrel-plug, but I don’t own one, so I don’t know the dimensions, pinout, etc.

Maybe a FAQ should be started for stuff like this…

Thanks for your reply! When my Jap PSU arrives then I can stop spending all my money on batteries.

Not a bad idea at all RunnerPack! OK i am going to throw my 10 pence in. Please correct me if i am wrong because there is a lot of people that use PVB, and have so much knowledge over myself, who has very little! This is not tried and tested yet as i havnt received my japan PSU. I will post the results.


Controller tap required.
Fits into VB controller.
2 Types available – USA and Japan, universal attachment.

PSU lead.
*Correction could be required*
USA tap requires NES/SNES PSU lead.
Japan tap requires Famicom/Super Famicom lead.
(I am awaiting a Japanese PSU lead to try on the Japan Tap I have bought).

Plug adaptor.
They ain’t gonna fit!

Step down convertor.
Virtual Boy = BANG!

I am awaiting my last bits to try this all out. Will let you know how i get on.

In the U.S., the NES and SNES use different plugs (and voltages; I think the NES one outputs 9V A.C. and the rectification/regulation is done in the console; THIS KIND COULD DAMAGE A VB!) on their respective A.C. adapters.

I don’t know about the Japanese systems.

Thanks for the correction, I was led to believe the US and Japanese NES/SNES and Famicom/Super Famicom had inter changeable PSU’s (something to do with standardization between old and new consoles that Nintendo wanted to achieve). Indeed the Japanese PSU I received today is for the Super Famicom and not the Famicom and works just fine.
