I just got a PS2 Slim, but I'm not a huge fan of ripping open my console and POSSIBLY screwing everything up by solding in a modchip. However, I did find this URL: http://www.thegiantstore.com/browseproducts/PSTwo-Slim-Flip-Top-Cover---No-Modchip-Required.HTML Now it CLAIMS that this method will play both PS1 and PS2 backups, both CD/DVD based. I was just wondering if this is a sure method or not? I'd hate to dish out $40.00 just to find out it ONLY plays PS1 games or CD based PS2 games only. Anyone have any information on it? Thanks!
