Yesterday i received my viper chip that i ordered from http://www.robotpig.com great packaging and delivery,very friendly and always available to answer questions,highly recommended. Anyway I installed the viper and found it quite easy if you just take your time.The only difficult bit was removing the heatsink as it is well pasted and too much twisting can damage the board. I was a little usure about leaving the modchip where it sits, but so far its fine. I leave the lid off when i want to use it, just as a temp measure until a new lid is released or i get my hands on a good mini DVD-R. So i have downloaded an Iso of PSO 1+2 and used Nero to burn the Iso on Princo at 2x closing the disc. How ever it didnt work,this morning i woke up and remembered i had a TDK DVD-R under my desk. I burnt the iso @ 4x with Nero and it works, so i am very happy. Just to let you know,i had no black screens or any problems in getting the GC to load or power up.
