Including crack in the CD...?
 

When you burn a image and you dont select ''finalise disc'' and there is still space left on it can you just burn the crack file later and it wont interfear with the CD autorunning as usual???

nope. burning an image always finalize the disk. multisession disk made by burning files only.

so do you guys put the crack on a flopy or something or just put all your cracks for all your games on a CD??

you could always open the image created with WINISO or others like it, and just make a "crack" folder with the crack inside ;)

I recommend UltraISO for that. It can handle any image file. ;)
