I ordered a Matrix Infinity mod chip for my PS2, and I'm currently waiting for it to ship. However, I'm a bit concerned about a few things... First of all, I've never soldered anything in my life. Having said that, I'm pretty sure I can figure it out. Here are my questions: 1. Does it matter what soldering iron I use? The instructions recommend a 15 Watt soldering iron with a 0.1 mm tip. 2. The instructions imply, but do not explicitly state that I should use 20 or 22 awg wire for the ground and 3.3V connections, and 30 or 32 awg wire for the rest of the connections. Is this correct? 3. Do I need to clean everything with solvent first? Is this necessary, or just recommended? 4. My PS2 is fairly old, and doesn't read the disks with the blue/purple backs(gives disk read error). Does this mean my laser is weak? Will it be able to read burned media? 5. Does anyone know of any good tutorials that will help me install this thing? All I can find is installation diagrams. 6. I'm kinda confused about my PS2 version. It has 8 screws on the bottom. The number on the back is SCPH30001R. It has the electricity warning stamped on the bottom. Is it version 4, or version 5?
