Where the heck is it? :) I tried disassembling the cbm-ii kernal, but
I couldn't get the vice monitor to work in bank 15. Single stepping
code worked (it followed the code), but it only printed 00 or ff
bytes, making it kinda tricky to figure out what was going on. I also
tried diffing memory (with peek from basic) between $0000..$03ff, but
nothing seemed to change. Frustrating indeed!

Ohhh. Where is this stored exactly? Is this in the kernal or the cc65
code?

K. You added this to initconio or crt0.s?

OK, good :) Could be an issue with my test program.

Right, but escape codes usually does something, I don't think anyone
will be surprised :)

Well, they do change the VIC colours, but that's probably not what you
want... Try this:
http://www.cling.gu.se/~cl3polof/color.s
bordercolor is now a null op when in VDC mode. The other two translate
between VIC and VDC palettes. Note that the VICE VDC emulation is
buggy and doesn't handle register 26 (background colour) correctly.
ldx #26
lda #3
jsr $cdcc
rts
works just fine on a real 128, but bugs in vice.

Great, I'll base any further work on your snapshot.
Is there any way of submitting patches over CVS instead, or is there
no approve/disapprove funcion in CVS?
