How did you get the OVR palette separated from the TIC palette? Whenever I try to change the palette for it, the TIC function gets the same palette too.

I set the palette in scanline function for the first line (0). This sets palette for everything drawn in TIC function. Then I set the upper palette at the end of OVR function so everything drawn in OVR uses this palette.
You can see how this happens in api_blit function. https://github.com/nesbox/TIC-80/blob/master/src/tic.c#L1934 At the start it sets the palette for OVR then it calls scanline(0) and sets the palette for everything displayed on the screen at the end it calls OVR function which uses cached palette and sets the palette for next call of api_blit. |

That's very interesting. Don't know why anyone would want to use the SCN function just to get a 32-color display with separate TIC and OVR palettes.
Yes, SCN() has been implemented to fit with the 3-char names of TIC and OVR, but left scanline() highlighted for backwards compatibility with older cartridges. It is basically just another way to call scanline(). |

EDIT: I realized the other day that a cart can have SCN() and the deprecated scanline() simultaneously. They run concurrently together.
