ps2 game booting...

[cl0ckw0rk]

hey, i'm havin trouble booting my ps2 backups with my modchip. Unfortunately i don't know what version my modchip is except that it's a fairly early model. I got it from modchip.com (which i now hear is NOT the place to get em) Spring 2001. I ordered it with a Gameshark so i could boot my ps2 backups but it seems that the instructions wont work. They say that i should first boot up my ps2, insert the cd, select to play the game with/without codes, then when asked to, insert the CD and press X immediately. I've tried this several times with multiple games but none work =(. If anyone could help me i'd be eternally grateful =P. And if Charlie responds, then i am eternally grateful...again. Thx in advance tho.
