Hi there,

I was wondering how to get the rgb values of a color in msx basic ?
If you for instance want to change a color, you can use color=(5,1,2,3).
But what command do I need to get the rgb values of color 5 ?

Yes, the VRAM addresses are explained in here

How ever if the software is not nice and does not update these values in VRAM then the information is permanently lost inside VDP and you can't figure it out anymore... This is pretty typical in games and demos... Naturally in emulators you can use the debugger interface to figure them out anyway.

openMSX can show it:
Advanced -> Toys... -> show palette

Proved its use to me quite a few times already Smile

the fun is that it's always visible and thus it shows fades as well. Very nice Smile
