just wondering
 

is it possible to convert a cd based ps2 game to a dvd, and if so how would you go about it?

It's a waste of time...

not really a waste of time, cause if you can, i dont see why you couldnt have 4 cd-r type games on 1 dvd5

it is possible but once again.....why would u want to???? if u already have 4 original cd based games why would u also want a dvd with the 4 games on?

I agree, its a waste of time and dvd-r's
