Curious why you don't favour the illegal op codes?
No real reason, I just never got accustomed to them. The ca65 was also used in default configuration, illegal opcodes disabled. I realized it rather at the end of the project and decided to put out that claim. Or as Ninja / The Dreams put it, once he saw it: "so there's still space for improvements".
The next couple of weeks, I want to set up a repository reflecting my "The first selfcoded A2600 demo" workshops, with the slides, example source code, template source code, etc. After that, at least two of the tools I coded myself will go open public: fridgegrid was already introduced here in the boards, and I also hacked up a tool called "apefat: A Poor Excuse For A Tracker", an editor for a slightly improved Music Kit by Paul Slocum.
