PS1 mod chips

[Toaster]

there is a new modchip out version 3 multimode wired as 6 wire
see link http://www.modchips-uk.com/
It is better for the ps1 (psone) If you still want to use your existing mod chip try wiring it as stealth mode ie connect on the extra wires and I would also recommend first trying to use the boot disk for the ps1. I cant find the link to it just now but e-mail me and I'll send it to you. (its very small file size)
