PSx2 dvd game backup up to dvd-r

[OSIAS]

Hey alright i have already been their my problem is this.

i have burned gta 3 which i own and burnt with nero ... i have
usb modchip. from modchip.com... i have several version of gameshark ver 1.3 and 2.0 but i can not get my backups to load.

from what the tutorial says on the site above it will only load with gameshark ver 1.7 or 1.9 .. so i take it this is the problem . but they said that is with the neo2.x chip though. sorry i am getting confused with all the chips out their and also on all the sites that sell modchips they all claim to boot dvd-r backup for the psx2 and they give with their chip gameshark ver 2 which i have so i am confused.......

look money is not the issue obviusly because i own a dvd burner, but i just want a rig that works without to much hassle, and plus i can not seem to find anywhere a gameshark ver 1.7 or 1.9 anyone know where i can get it. also i am already chipped but anyone know where i can just buy an entire bundle chip and boot software that will work for what i am doing. I think my ship could be old.. what chips would someone recomend. are their any that you can just chip your system and it will just load whatever you want yet ?

well if someone could get back to me i appreciate it, thanks...
