AutoKernel by Scott Hunter is a modified C64 kernel ROM that will auto load and run the first BASIC program on device 8 when the computer is turned on.  This would be a great alternate kernel for something like the Ultimate64, unfortunately this would leave you without JiffyDOS.

Also included is a program by Ray Allen called SnappyLoader which is a BASIC menu that can be run by AutoKernel to assist in loading other programs.

U64 Run by TTL is a neat little command line program you can use from a Windows shell to load and run a program on the Ultimate64 (Gideon).

Ex. - c:> u64run.exe 192.168.1.64 test.prg

U64 Streamer v1.2 by M.F. Wieland is a Windows utilitiy that can accept an audio and / or video stream from the Ultimate 64 (Commodore 64 FPGA) and capture screens or video from the stream.

U64 Streamer v1.22 by M.F. Wieland is a Windows utilitiy that can accept an audio and / or video stream from the Ultimate 64 (Commodore 64 FPGA) and capture screens or video from the stream.

U64 Streamer v1.23 by M.F. Wieland is a Windows utilitiy that can accept an audio and / or video stream from the Ultimate 64 (Commodore 64 FPGA) and capture screens or video from the stream.

This is a snapshot of the documentation for the Ultimate 64 Data Stream as of May 14th, 2020.  Here is a web link to the original source.

What is it?! This board is a hardware implementation (FPGA) of the entire C64, and it includes the Ultimate-II+ as well. An ALL IN ONE solution!

Changelog:

• Sprite Collisions.
• Illegal graphics fetches.
• Sprite DMA timing.
• Nuvie Player.
• NMI handling improved in 6502.
• Illegal reads when BA=0 masked out (“PLA” issue)
• Added debounce on Restore Key.
• KCS power cart fixed (sprite graphics error)
• HDMI/DVI Compatibility.

.. and there are many improvements not present in the changelog.

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.

Apparently the version numbers are hex and not decimal.

Differences with previous official release V1.06

• SID has been improved quite a bit.
  • The internal SID is now consistently referenced as "UltiSID", to avoid confusion with other SID products.
  • Various bugs, like the phase of the filters, and the routing of Voice 3 when the VOICE3OFF bit was set have been corrected.
