Player burned PSX and PS2 games (including those that are JP). I would also like to know if it's possible to get an Action Replay backup (if there's such a thing?) running using a modchip. I have a slim PS2, but I have heard using modchips ruins the laser in like an hour. Some websites sell laser fixes, but I don't know how reliable those are. I'm not interested in getting an external hard drive or anything, I just want to run backups without using a flip top and swap magic. I have heard of about four different chips, but I really want to know which one is the most popular and has the most features. I would really appreciate it if someone could help me.
Could you please be a bit more specific and tell me if can do the things I'm asking for and how it compares to other chips?
I agree Duo3 is a good basic chip and will cover all of your needs, if you can get your hands on a Matrix Infinity or a Crystal Chip 2 I'd recommend one of those. I myself have a slim PSTwo with a Matrix Infinity.
