all questions are answered in due course, and theres always a second opinion

now then, i took the time to dig out my superfami ps for ya-

input- ac100v(50/60Hz)
unknown 18VA
output dc10V 850mA
(+)---------(.-------(-)

so the polarity and output are the same as the snes ps, i'm not the final word on this (that might be FAbombjoy) but i'd think you can use it.
