OK, at this point I just want to READ the logo, not to flash a new one. Should I delete the xrgn,16,2:/16.bin line from the update.txt file?
OK, have extracted from both the Garmin and the HD. Both files are 800x480x32, but the Garmin is 10KB in size, while the HD is 25KB. Both are in .png format.
Would it be accurate to guess, then, that the HD file is too big to display with the 595 firmware? If I can reduce it in (file, not physical) size, it might display?
Spoiler: large images
Edit:
SUCCESS!!! All sorted, now displaying my reduced size HD Logo on Bootup.
A million thanks to you Butters!
