1.3

  • Boot time reduced to 5 seconds for both SID engine types.

1.9

  • First release of BMVIC20 available

  • Updates BMC128 available with a few fixes

  • cmdline.txt has changed and should be udpated:

    PSA:

    If you are in the habit of just updating the kernel file, best to update cmdline.txt with this release. canvas_height,canvas_width parameters have been renamed to vicii_canvas_height, vicii_canvas_width to distinguish between C64 and VIC20 (or other future) video chips that need different sized frame buffers. Also, I changed the way the emulated display is drawn to fix some unused black border issues on both C64/C128 and VIC20 so the C64/C128 frame buffers are now a different size. If you find your video output is squished after this update, best to confirm you are using the new cmdline.txt settings. This change 'zooms' the video in a bit so more of the screen is used. It also looks better on composite out.
