Possibility to accept frames having 4 palettes

[fabri1983]

Hi Haroldo. Greetings from Argentina.
I'm following your project. I love the idea of having a video player for intros and cinematics.
Also I'm implementing an algorithm which produces up to 60 colors (4 palettes, 15 color per palette, 1 transparent color per palette), but I'm not quite familiar with the internals of Genesis arquitecture yet.

Is there a way to adapt your code in order to accept frames with 4 palettes?

Hello, there. ;)

Yes, it would be possible; the main problem there would be to write a conversion tool that separates the palettes for each individual frame; rgbquant-sms, which is already being used by the video conversion tool, can kinda do it, but not really:

• It would have to be adapted to support the Sega Genesis Palette (for now, I'm using SMS palette):
  • Issue: Extend to support Game Gear and Sega Genesis palettes. RgbQuant-SMS.js#3
  • Unfinished experiment: https://github.com/haroldo-ok/RgbQuant-SMS.js/tree/more-palettes
• Also, while rgbquant-sms has support for multi-palette conversion, it does not seem to work very well, and would probably have to be further polished;
• Finally, SGDK's "RESCOMP" tool does not seem to be able to convert images with multiple palettes, meaning that it would probably be necessary to create a custom tool to convert the individual frames into a format that Genesis can use;

An alternative would be to completely skip rgbquant-sms and RESCOMP and create a tool to convert the graphics; it would have be able to:

• Reduce the tile count;
• Use all 4 Genesis palettes;
• Convert the output into a format that Genesis can digest, proably with compression.
