It's weird that is doing like this. The disk itself is in "mint" condition, not a single scratch. Guess any disk based format just decomposed it self over time.
With the PlayStation classic do take the similar ISO files when rip it using the "ImgBurn" but before hand, the console need to be Software hacked with a USB.
After that success it just need to extract and transfer the file of the game "me ripping them" to a specific folder, then set up the USB on the console.
Its been successful so far with my collection of games I have on my shelf, except for this Alien game I have on my shelf.
