C64 Ultimate Wiki

A selection of quick tips and tricks to make your life with your ultimate device even more fun!

• Experiencing garbled text and/or graphics in a demo or game? Check the TURBO BOOST settings and make sure to have set it to OFF. Even having Turbo set to 'Manual' mode, at only 1 MegaHertz, can throw off the timings needed for these games or demos to be displayed properly.

• CommoServe hack to include 'Assembly64' - See commoserve_hack_to_include_assembly64

• It has been reported that a USB thumb drive is about 3 times faster than an SD card. So if loading speeds are important to you, use a USB “stick” for loading larger amounts of data

• Did you know that you can play Amiga style .MOD files on your Ultimate device? If you don't have any mod files yet, start at https://modarchive.org/ and download a .mod file of your liking. IMPORTANT: Only .mod files will work. Other formats, like .xm, .it, .s3m, etc. are not compatible with your Ultimate device.

• If you have software (usually a demo) that refuses to work on your Ultimate device, make sure to do the following:
  • Turn Turbo Boost OFF
  • Set Drive A to 1541 mode
  • Disable Drive B
  • Disable IEC drive
  • Disable IEC printer
  • If using a fastloader (i.e., JiffyDOS), make sure to disable that too.
