How can I insert the genesis color pallet
To aseprite
hi there! usually you would load palette in gimp’s gpl format, since aseprite can’t generate a palette with more than 256 entries from image.
example of gpl palette:
afaik there’s a lot of discussion over the actual rgb values of colours in cases like sega consoles, so i can’t comment on whether this is a proper palette or not.
how to load / save palettes:

So in GIMP, how would you convert an image to use the Genesis 512 palette? You can’t just convert it to an index image as the palette has more than 256 colours.
I’m trying to convert a true colour image to use just the Genesis (RGB333) palette range. So it will use the full 512 colours or at the very least, convert it down to 256 colours, but do it using the full RGB333 range (512 colours). Otherwise, you are missing half the colour range off.
Since GIMP has similar limitations to Aseprite, one option is Krita’s palettize filter.
I don’t know much about the Genesis, but if it has a limit of m colors per n by n tile that you need to recreate, a palette match in Krita wouldn’t replicate the limitation anyway. Compare these two (assuming they’re not compressed once I post this reply):
A quick google search turned up these tools:
Nobody seems to agree on what the Genesis colors are. I used this

Based on this wiki. It is not the same as a linear calculation to convert between RGB888 and RGB333.

Thanks you so much for the first link to that YouTube video. Using that online converter, I was able to load up a true colour image, set it up to RGB333, gave it 2 palettes of 256’s each and was able to convert the image into RGB333 using the whole colour range of 512 colours (it did a much better job than trying to convert using a selected 256 RGB333 colour palette), from there I loaded it into PhotoShop and set it to index. Which worked out it was only using 138 colours in total, but the fact that the conversion was taking all 512 colour into consideration, gave it a much higher colour range to play with.
By the way, this isn’t for a MegaDrive game, but for a Spectrum Next game, but both use RGB333, just that the Next can display a lot more colours on screen.
