Well this is how it goes, i think i have a neo 2 or 2.2 chip in my ntsc ps2 v4, however i dont have a gameshark 2 so my questions are: 1. can i play ps2 DVD-r games or DVDRIP games without a gameshark? 2. i can play only a few psx games- i downloaded crash bandicoot 3 (pal), final fantasy 8 cd 1 (ntsc), and some stupid dbz game (pal)and they worked (not directly, i had to press the reset power for a few seconds longer)but when i used xenogears (ntsc) cd 1, megaman 6X(ntcs) they didn't work and i cant figure why, when i used the same technique on these games, i was only able to get to the ps logo and then it stopped. you have any idea why? i burnet them all X4 and on the same media type (silver line cdr 700 mb 80 min) 3. will game shark version 4 work well with my neo 2/2.2? Any replay will be appreciated !!!!!!!!!! thanks!
