have you tried booting an original US or european game with the region X swap?
if it works, you have an origa chip most likely. if not, it's most likely a cdr-only swap chip.

First of all thx.
According to D Soldier th console I have has item 1 but not 2 its a version 4 I have?

All the games I have is cdr only and I guess that I have the origa chip as you say. What can this chip do? Can I play any DVDr copy.
Any web sites or articles that I can learn about this chip. Also if I want to change another chip can it be done and what is the recommend modchip? Can I use the external usb mod? Also do I have to remove the already installed chip?

Thx
