Next questions: In some ops is half carry "undefined"... e.g.: ASL, NEG, SUBA etc. What does it mean on a real machine: Half Carry remains at the last value? EDIT: btw. there also only a few ops that affected the half carry are only ADCA, ADCB and ADDA, ADDB and ANDCC, ORCC All others are "undefined...

Thx!

One Question:

TST Extended $7D is it a 16Bit test or a 8Bit test with just a 16Bit address?

EDIT: Seems to be that it's only 8Bit with a 16Bit address, isn't it?
So this commit https://github.com/jedie/DragonPy/commi ... bd5ec14db6 is ok, or?

I have the Philips Brilliance 200P3, now.

Dragon 32 PAL works fine, color and clean.
Dragon 64 works not good: no color
Dragon Tano: not shown clean: Green color, but blured and some vertical lines missed.

I will add this on the Wiki page.

btw. your compiled version of v09 doesn't work for me. It doesn't display Welcome to BUGGY 1.0

btw, the 6809 JS sourcecode is here: https://github.com/maly/6809js
