If I recall correctly, the center pin is + and the outer section is -

Can anyone verify this? I'm going off of memory.

If you have the original power adapter, it will tell you. Or, if you have a multimeter you can see which one is - or "ground". Do you know how to do that?

was I not clear about it in the PM?

My wording was a little confusing, I guess.

WHOA!!!!!

wow, im dumb

collin did answer this in that message

wow, ok thanks to everyone else though

however, do i use both the negatives or just one (or is one ground, and if so where do i solder that ground - to the ps1 screen ground or the N64 ground or what?)

thats pretty much the standard convention.

if your grounds are connected, it is likely that it does not matter. if you have current issues, you may need multiple ground connections or lower gauge wire.
