 Re: XeO3...

I thought about a screenmode like the one chicken proposed. My conclusion was it is only suitable for demo-effects where you can spend most of your memory only for the screen-mode and define the memory-layout in a way that "address-generation" is easy wink

I've set up a screenmode that consists of 25 charsets and gives you the possibility to have something like a charset-based bitmap with two buffers and the option to do a quick-erase. (40 chars frontbuffer, 40 chars backbuffer, 48 chars "free patterns"). The "Do-I-Need-To-Mix-Graphics"-Test works the same way, Mike does it:

LDA screen
BNE i_need_to_mix

Anyway: For a game i think you need more flexibility and Mikes approach suits better.
