I was playing around with the Dolphin emulator and installed a BIOS file. I tried to open the BIOS and it boots up but there was just a Gamecube startup animation and a message box spoken in Japanese and I couldn't read it. I translated it after an hour and it reads that it failed to read the disc and to read the manual. I was really confused at that point. I don't know how the disc is dirty or something and it's just a file on my computer. Here I now end up... still wondering how to fix this. Can anyone help?
For your information:
-Emulator used is Dolphin
-I use macOS 1.13.3 High Sierra
-I tried Mario Kart: Double Dash!! and Super Mario Sunshine to run BIOS
