burn a cd
 

i have a game for dc on my comp but the file is too big for a cd . what do i do to get it on a cd

What do you mean by "I've got a game on my comp" ?

Is it an image ?
If so, just burn it on a CD using the proper burning program (use overburning if necessary).

If it's a GD rip, downsample some of the files...

If the file is a .cdi then use DiscJuggler v 3.50 to burn it if it is in all zip file eg, .r01,r02 or .001,002 use winrar to extract them then burn the .cdi file
