Jinke is on holiday until the 9th. It should be relatively simple for them to add a V5 version of Logomaker. It is worth doing, because adding your name a phone number (say) to the boot and shutdown images could help if you loose your Pocket Pro.
If anyone want to try writing their own Logomaker it looks pretty straight forward. OpenInkPot has the Hanlin v3 firmware file format
, which includes a block for the logos:
startup and shutdown logo.
Logos are uncompressed headerless 2-bit gray 800x600 images.
Every byte contains values for 4 consecutive pixels. Images are stored line-by-line from left to right inside line, from top to bottom.
and the V3 logo.bin seems to be exactly this.
Based on how the V3 logos came out on the V5, I think it is simply using one byte per pixel (3 bits used out of 8).
If someone wants to do this, I suggest also adding the capability for extracting the existing logos from the firmware image (v5setup.bin).
