You'd have been better off posting this in the Console Forum. :iagree:
Right, let's start from the top. Don't use Alcohol as your burning app. :disagree:
Back in the days when I used to make backups of my PS1 games, I used to use CDRWin to rip and burn to CD-R. I can dig out a guide for you if you want.
About that emulator, I used to use the same one myself a few years back. I had the same results as you - I could never get it to work off a PS1 CD-R in my CD-RW drive but I could get the game working off the Hard Drive.
I don't know why this is. Maybe it's a bug within the emulator software, I really don't know.
And in any case, I thought that you said you've got a PS1 console? You know, using an emulator to test a game really isn't an efficient way of finding out whether the game is a good working copy or not. :disagree:
You really need to try the backup copy on your PS1 console. If you use CDRWin correctly, then I can't see a reason why you shouldn't get a fully working backup copy of your game.
