Flashing your VERA comes with the risk of causing an unbootable system. Please do not flash unless you have consulted with the X16 Community in the Discord, preferably have access to an external SPI programmer, and/or are otherwise confident in the process.

Instructions:

Download VERA_V0.1.1.BIN and FLASHVERA.PRG, and place them on your SD card.

Rename VERA_V0.1.1.BIN to VERA.BIN

Insert the card in your Commander X16 and invoke the flash utility:

LOAD "FLASHVERA.PRG"
RUN

and follow the on-screen instructions.

What's new:

  • 240p progressive mode for NTSC and RGB, selected by setting bit 3 in in DC_VIDEO
  • Separate H/V sync for 15KHz RGB can be enabled via clearing bit 2 in DC_VIDEO while the RGB output is active. The default is composite sync with bit 2 in DC_VIDEO set. This is the same bit that enables or disables color burst in NTSC mode.
  • VGA sync polarity corrected, should improve compatibility with CRT VGA monitors
  • HSync position corrected in NTSC mode
  • Version number accessible in registers by setting VERA_CTRL to $7E and then reading out $9F29 for 'V', followed by major, minor, and build number (raw values) in $9F2A, $9F2B, and $9F2C respectively. Remember to stz VERA_CTRL afterwards.
  • other minor fixes

FLASHVERA.PRG release is from https://github.com/mooinglemur/flashvera/releases/tag/v0.2
