what should i use to open these? they are ( or should be) installers for some games...

Use Dameon 3.46 to mount the cue files for the game and it should begin install, the cues are used to access the bins. Just mount the image and you'll be good. You'll have to unmount and mount images into the same virtual drive. Say you have 3 cds. Mount the 1st one and install, then when it asks for the second one go back to dameon and mount the 2nd, do the same for the 3rd.

daemon tools work well, it's what I use to mount an image. if all you want to do is look inside them, get a copy of isobuster and open the .bin file.

ok, i got it to work with one of them, but with this other set of files i only have the .bin files not the .cue to load the image of...

just mount the bin. Same thing regardless.

Yeah just mount the bin.

if you have alcohol 120 you can also mount them. but if you don't use deamon tools.

.cue/.bin can also be burned to CD if you have fireburner, or just about any burning software. i used to burn games to CD until i got daemon. it kinda sucks, though, when you install a game and delete the .bin files and then have to reformat and you want to install it, you have to track down a game that is 4 years old on the internet! (glad i burned simcity 4!)
