Help with ISO files

Hello! I have 4 ISO files, i used Daemon to mount the disk 1 ISO image, but when the game starts, a message pops up saying to insert the cd and start again. I tried extracting to a .cue file and it still does the same thing. Any suggestions?
Thank you for your help!

you probably need the games nocd fix.

Google for it. You should find it somewhere

ok thats a bummer. Thank you!

Try burning it to a CD and see if it will work from a CD.

Either use the originals (hint!!) or burn the ISOs with the program you have created them with.

end of the line.
