Firstly: if you have the viper mod chip installed, is there any need of doing the region mod which allows you to play all world games. 2. Does the viper read ordinary CD or just DVD's. just a 3rd point, whats the point of cutting the inside of your gamecube inorder for a CD to fit, why not just cut the CD. the games are surely not that big OR am i wrong.
No region mod needed to play all of the worlds game with the Viper. It's not the viper that reads the DVDs it's the Gamecube, and the gamecube can only read DVDs Yes, some people like doing weird stuff to their gamecube, I used to cut the DVDs, but now I use ridata mini g-04s.
