I have a hard-modded ps1, fat ps2, and a soft-modded ps2 slim and ps3. I don't like having a bunch of systems out, especially since I have other consoles. So would like to use as little space as I can. 1: How are the later gen playstations at playing the previous gen games from a purest's standpoint? 2: What are the options for playing ps1 game backups on a ps2 slim? As I really like the ps2 slim. 3: Are running games from usb on the ps2 slim really that bad? I would really like to use it. 4: Can someone point me to how I can get a dualshock 4 running on a ps2? usb is fine. Thanks for any help anyone can provide.
