Could you please point me a bit further in this direction? Such as
example code? I've looked around for quite some time now and have
seen nothing but the blitter line-mode stuff that I mentioned.
Unfortunately, I'm not an assembler programmer, but can hack a bit
once I know where I'm going. (What's a DDA?)

Thanks,
