My problem is how to generate a 16 pictures colors with a 256 colors palette. I succeed to display the bg1. ...

Hello! In mode 3, I must use an unique 256 colors palette for the two backgrounds (256 and 16 colors) or can I use 2 differents palettes? Thanks!

I'm still looking for all Graphics and Sound software for Emulator SE/ IS Character or IS Sound.

For information, ISAS and ISLK works with Super FX and SPC700 code, just put the good ISSND or ISSFX pseudo instruction in it.

Sure, we are talking about Intelligent System assembler/linker/debugger manual not the common snes one.

It's very usefull if you want to code with it.

I send you a MP for a link.
