Download the latest version firmware to the removable media in advance.

Create a folder called “package” on the removable media, and then download the package firmware (xxxxxxxx.pkg) to it.

  • Do not put multiple machine firmware programs on the same SD card. Copy the only model firmware you want.
  • If you download the firmware package to the “romdata” folder, which is the one normally used, the firmware package cannot be updated.
  • When updating the firmware package of the same model, be sure to download each version separately. If you download multiple versions for the same model, only one of these versions is displayed on the machine’s operation panel, but which version is displayed is unpredictable.
