the pad-113 is correct
https://gamesx.com/wiki/doku.php?id=repair:pcepowersupplies
which is too narrow? the power supply plug or the input jack on the system?
if that is the one you got from me a while ago, neither the power supply nor the power input jack were modified from original.
Yeah, it's the SuperGrafx I got from you. I think that I sold my old SuperGrafx with the replacement power supply yours came with, because I already had a PAD-113 and thought I was set. I must have only ever played it with that replacement supply before playing it hooked to a Super CD-ROM.
The tip of the PAD-113 I have does not fit the SuperGrafx. I just ordered a substitute from retro game supply for now, which everyone seems to trust.
My Super SD System 3 has compromised picture quality when using a cheap replacement power supply, so I really want to try official ones.
Thanks for your help guys.
