Absolutely. Have fun,OP.

Must resist...

anyways my giant pic on the end of page one is getting plugged in now to my 1000yen famicom.! a new PSU will cost more

Just had a look at that PSU on page one - only outputs 500mA! That's really weird. The Sega Megadrive 1 PSU is rated at 1.2A.

The SFC needs 850mA. Be interested in seeing what happens, might not turn on.

I wonder what that PSU was originally for?

No Idea, the remote for my Akai CRT doesn't work so can't tune anything in, so skuppered again

Someone/something really doesn't want you to play that console

I think I'm gonna go for a universal PSU from amazon

I need a DC adapter for my Telescope clock drive anyway and it looks like this one has enough juice to power the SFC

Fingers crossed

Now I just have to be patient and wait for payday

Ya it's the variation of 9v to 10.5v that's the problem and with that the changing mA values. With a megadrive PSU the console itself will heat up but with a step down transformer the transformer not the PSU and console will heat up as designed.

SFC has an protection diode on the power input. While in theory you wont actually damage the system by connecting a PAL PSU to it it will cause system to overheat. After that it will run but won't run right because it will be powered with half-wave rectified current, which is not satisfactory even after smoothing (there's a 1000uf capacitor inside the SFC for that purpose). You will get humm on the audio, wavy video and possibly the wrong colors. Sometimes it wont even play(Raises hands). Had a Super Famicom for 10 years and it happened to me.

DO NOT TRY THAT on a FAMICOM as it has NO DIODES on it's input. You will have a fried 7805 voltage regulator in that case.

As I said it will work with megadrive PSU though.

I don't think the regulator is going to complain that much if it's half a volt over, especially if it's tied to a good heatsink.

Understandably, the input mains voltage determines the output voltage, but that can easily be measured by a multimeter if you feel it might be over 10.5v.

It's the amps not the volts that will kill ya!

Nope. Look up ohm's law.
