zip.png Ultimate 64 Firmware v1.06

Ultimate 64 firmware v1.06:

  • SpeedDOS Parallel Cable (needs e.g. DolpinDOS roms)
  • Interface type: Ultimate Menu picture overlay (HDMI-only)
  • USB keyboard support. Like earlier firmware, press scroll/lock to enter/exit the Ultimate menu.
  • Replacement of Charrom and BAISC

Note for the Ultimate 64:You will need a kernel, basic and character rom after the upgrade. These roms are not included in the update. These roms are distributed with vice-emu, but you can also find them on zimmermans.net.

For instance, you could use these roms: 901225-01.bin (char), 901226.bin (basic) and 901227-03.bin (kernal). Roms with the .rom extension should also work.
