Changing Kickstart Boot image
Is there any current way to alter the bootimage?

No, it is currently hard-coded into the bootimage.kmod. This may change in the future however.

Can't see on video, but is it 256 color image dithered well, or true color one ? If you understand how bootimage.kmod works , maybe you can also write new one, with "prefs" which will give user ability to choice boot image whatever they want ?

Re: Changing Kickstart Boot image
At the moment, im using un-dithered images as the output compressed image is smaller than when using floyd-steinberg dithering. At present I'm just re-arranging the set 138kb kmod file(through its ELF section padding) , thus my compressed image must be under 136kb. They are 256 colors, but as I'm not modifying the code that decodes and displays the image(that will be Hyperions job if users 'really' want it, which I doubt), we are limited to 640x480x8bit.
Once I learn how to stretch an ELF file while maintaining all the internal jump tables and address references then I'l be able to add compressed images larger than 136kb. Of course Raw images 640x480x256 are 302kb without compression. Again this is a hack, but yes if the Dev team don't see it as a problem, i will make it as a 3rd party picture changer with prefs etc.
