I wanted to know if i could put adf file on a cd and play them on my amiga,
There's a program that let's you mount ADF's on the Amiga, so in theorie this could work for games that don't kick the OS out the window. And offcourse if the game doesn't need to write to disk..
Another way would be to use WHDload or similar, install the games to HD, copy the diretory to CD and make a script that makes the needed assigns (if any) point to the location on the CD..
