PSX Change
 

I wasn't sure whether to put this in PSX or PS2.. it could go in both... but anyway. I got a non-solder mod in my PS2 (Tho no AR/GS, only a RegionX). Now could I use the PSX-Change to boot PS1 copies on my PSx, bearing in mind the non-solder chip would take the role of the spring on a PS1?
