I have recently manaully installed a DMS3 Mod chip. After thoroughly checking connections on my PS2 v4 Gap main board like ensuring points D&E are isolated as well and using thick wire for a 1cm ground cable, the system just acts as though there is no chip installed. All original Games & DVDs work fine, im just not having any joy when trying to load up my Backups ! Has anyone else experienced this ?? Please Help!!
