SDGK 2, 3 and 4 palette support for backgrounds?

[matteus]

I know this is probably a request that cannot be achieved? But could we possible have a VDP_drawTitleScreenImageEx function with multiple palette support? I just know my video player could do with the added colour support Is it an issue with ResComp that stops this being possible?

VDP_drawTitleScreenImageEx ?
You can use VDP_drawImageEx(..) method and having multiple palette, actually rescomp support multi palette image so you can just PAL0 in your base tile but PAL1 to PAL3 will be used as well if needed

Really!?!? So ResComp already supports multiple palettes??? Wow why didn't I know this lol

oh I see but you can't give it a 45 colour image and it fix any issues it encounters with certain tiles

tile [1,0] reference different palette.rm

Actually you can have image up to 64 colors but in fact you can only really use 61 colors at max as 0 index of each palette is transparent.
Indeed you cannot have a tile having more than 16 colors and you should have each tile using independent palette so definitely all palette work should be done before (tile 0 referring color0-15, tile 1 referring color 16-31...) and i don't know which tool you can use to make that easily. If you use a soft as "tiled" it can generate a global PNG image from map and tileset but i don't know if it preserve the palette information.

Is there a standard editor people use for this type of graphics work? I've done a search and there seems to be loads! If you know of one that is particularly good I'd be very grateful!

Personally i'm using Tiled and Gimp2, but they don't have native Megadrive constraint, you have to extra work to do for that.
You should check this one, made specifically for Megadrive :
