I just bought the "Undiluted Platinum" modchip.. I started to open my PSP to install the chip and soon realized that I had to almost completly strip the PSP to get to the main board. I've searched the net but havn't managed to find a complete guide on how to open the PSP. Anyways I managed to loosen every part after an hour of strugling only to discover that the tracks I was supposed to solder the chip to was ridiciously smal. I almost laughed when I saw the tracks. Its 9 tracks on a 2mm wide area, and you have to scrape off the soldermask to get through to the metal. You get a tool to place as a guide which is more anoying than usefull. If you should be succesfull in removing the solder mask, you have to get the wires to stick without shorting out the other tracks.... I've chipped about 20 ps2 without any problem, but this to me is a lost cause.. Have anyone had any success installing this chip?? If I could find some alternative solder points maybe I could get it to work?hmm, any ideas on that anyone?
