I tried using many different progs an it wont work

i have a game in 4 cd parts, each one has a cd#.img,sub, and cdd. i tried mounting the cdd with deamon, but it just opens the cd folder. then i used magiciso and made the mounted cd an iso, tried to mount that an it didnt work. then i tried to burn the ccd with cdclone but when i put the disk in it just opens the folder again. in the cd folder theres the game info, but theres also a .img file, is the problem revolved around that? and if not do you know how i can get this to work?
