It is a long time dream for many of us that"Is it become possible to play my favorite game in XBOX or PlayStation".Now I could assure, this is possible, with a small chip called mark chip I am now able to play any game in my new XBOX irrespective of the disc type and without any compatibility issues.This simple upgrade enhances my gaming experience and at the same time I now got the freedom of choosing from a lot of collections out in the market.I not sure that it also works for PS as I don't have one.But still my friend who uses PS2 accepts that it works very well for PS also.
