I've decided to install a modchip into my PS2 and I have the following options: - Matrix Infinity - H20 - DMS4 I.Z.I. pro - Mars The price of each differs, the highest being DMS4. I want the modchip to have the following features: - Playing DVD-9 backups/imports. This one is absolutely imperative, this is what I'm really looking for. - Playing DVD-5 backups/imports - Playing PS1 games (originals/imports/backups) - Optional: Stealth mode, if I ever spring for an ethernet adapter and want to play SSX3 or MGS3:S online, but I don't see that happening soon. Any ideas? Thanks in advance!
