You should use ADFBlitzer to make adf copies of all your games disks so that you avoid problems in the future. I have an English copy of my Flashback disks. Just that I note that number 1 disk is the install disk. Not sure what language you are likely to get.
I have all my software and games in adf format. That way I can can simply have my originals in storage and never need to get them out again.
If you get stuck let me know.
