Oh, man. This brings back memories. I did this every time I loaded any game into the system. My PS1 had issues with the balls on the disc spindle that locked the disc in place. I had no idea and had so many issues with discs not loading until I discovered it. Then it became the disc equivalent of popping the cartridge out of the SNES and re-seating it until it worked. Eventually, I had to replace the balls as they fell out but as a broke college student, I just crumpled small bits of aluminum foil into similar sized balls and stuffed them in there. Worked great after that.
