UK1541 aka ''Ultimate Killer'' is a floppy drive emulator developed by Krzysztof Switajski aka [https://csdb.dk/scener/?id=6557 Kisiel/ICON]. Unlike the [[1541 Ultimate]] or the [[Chameleon]], this device is microcontroller based and does not use a FPGA - which makes it relatively cheap. Also since the device only connects to the userport (for power), it can be used with a C64/C128, VIC20 or Plus4.

    UK1541 aka Ultimate Killer is a floppy drive emulator developed by Krzysztof Switajski aka Kisiel/ICON. Unlike the 1541 Ultimate or the Chameleon, this device is microcontroller based and does not use a FPGA - which makes it relatively cheap. Also since the device only connects to the userport (for power), it can be used with a C64/C128, VIC20 or Plus4.

    • Drive 9 - drive number 9, switch set to number 9 (core reset required)

    Firmware

    The most recent firmware update files can be found here (last modified 2018-02-26). Updates are announced in a Forum thread (requires login), which unfortunately is also the only existing "change log". No older versions of the firmware are provided here, because the device does not allow to downgrade anyway.

    Updating

    1. Turn off C64
    2. Prepare empty SD card, FAT32 formatted
    3. Copy firmware update files to the Root of the SD card
    4. Plug SD card into the UK1541
    5. Turn on C64
    6. Firmware will get updated, wait until UI shows windows
    7. Remove files from SD card after update
