I haven't tested illegal opcodes myself yet, but I can't see why they
shouldn't work on a real VCS. Internally the 6507 is just the same as
the 6502, only some of the pins were removed.

This sounds more like a problem between the emulator and your soundcard.
Do you have a small example program that demonstrates this effect?

I'm probably even worse than Piero at playing this game, so I'm also
for a rookie mode. I think the main problem is that the ship turns a bit
too fast, so that exact maneuvering is very tough.
Since I can't get very far in this game, I don't what's missing. But
If you still have plenty of space, maybe you could put a PAL mode into
the same binary. And if you don't have an agreement with Firebird, you
might want to think again about putting their name in the game and the
documentation.
