Release Notes

U64 Differences with previous official release V1.06

Note:
When you reset configuration, you will need to flash the kernel, basic and character roms 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.

If you use your U64 with HDIM or RGB, please make sure to change the video output back to HDMI (from DVI) and/or to RGB (from CVBS + SVideo).
