[asheet]

Hi
I have a Playstation 1 and all orig CDs.
When I bought a couple of Local PS1 Game CDs, I found they don't work on my PS1 but plays wll on my friend's PS1.

A quick websearch revelaed that I need to get a Modchip fitted on my PS1 to enable it to play all Local CDs.

Pl tell me where Can i Get this modchip fitted at Mumbai and what is the cost for it.
Also, if u can give me some links on know more on Modchip it will help as the net links are all pornsite type of links.
Thanks
