Upgrade THEC64, THEC64 Mini and THEVIC20

Firmware upgrades for THEC64 and THEVIC20 range of consoles provide new features and correct issues. We always recommend that you upgrade to the latest version of the firmware. The latest version also contains the changes from previous versions.

Ensure that your USB memory stick is formatted using FAT32 (with an MBR) otherwise the upgrade file will not be detected. When updating please ensure that your THE64/Mini or THEVIC20 only has one joystick or mouse connected to it. If you are upgrading a THEVIC20 or THEC64 we recommend using the rear USB port for your memory stick (note THEC64 Mini does not have a rear USB port). We do not recommend plugging the USB stick into a USB hub to perform the upgrade. See the FAQ for further details.
