Why go to all the effort? The SNES uses Power Tip R, both Maplin (UK) and Radio Shack (US) sell these, it 6.9mm with a 0.7mm tip (commonly called 7mm by 1mm) the NES, Famicom and SFC use Power Tip G, 5.5mm with a 2.5mm hole. The NES (UK and US) and SNES (UK) uses Tip G at 9V AC at around 850ma (although more is fine), where as the SNES (US) uses Tip R at 10V at 850ma (although 9V at 1A is fine too) with a Negative Tip. The Famicom and SFC use Power Tip G at 9V at 1A with a Negative Tip, you can use a Megadrive / Genesis PSU on these with no ill effects.

Actually the Famicom and Super Famicom likely use a 2.1mm barrel connector, and the European NES and SNES (and likely US NES) use a 2.5mm barrel connector. You can see the different pin sizes in this comparison picture from the thread I linked in my first post:-

I really appreciate your reply, and I dont mean any offence, but the above sort of error is the exact reason why I want to clarify for certain what the plug sizes are. I realise some people might see this an unimportant, but it interests me and I hope to to add the info to the gamesx wiki so I want to make absolutely sure the info is correct and not half-guessed.
...I did put in the first post:-
