The encrypted ISO (if any is detected) is decrypted on-the-fly during emulation.
Supported ISO encryption type:
Decrypted(.iso)3k3y(decrypted / encrypted) (.iso)Redump(encrypted) (.iso+.dkey/.key)Unsupported ISO encryption type:
Encryption type detection:
The encryption type is selected according to the first matching encryption type found following the order below:
Redumptype: ".dkey" or ".key" (as alternative) file, with the same name of the ".iso" file, exists in the same folder of the ".iso" file3k3ytype: 3k3y watermark exists at offset 0xF70NOTE: Both
3k3yandRedumptypes have been tested without performance drop compared to Decrypted ISO and Folder formatBUG FIXES
