Psx backup issues

:confused: Hi everyone first off is it legal to dl a game as backup as my original is scratched/damaged if so then how??? eg say i had game.ccd, game.ccp, game.cue, game.img, and game.sub what would i do with them to make a backup using alchahol 120% ps i am new to pc and all this stuffand only have basic knowledge, thanks all in advanceā€¦ pps if this message is not legal sorry!!

you can read about it on .i hope that you really own the game, if you made the images by yourself you should know that these are clonecd image files

*.cue the cuesheet
*.img the image file
*.sub the subchannel data
