No emulation of the ANC opcode

[omarandlorraine]

I hope this is the right place to file this information!

This is about an illegal opcode I don't see an implementation for in this crate. The instruction behaves like and # except the carry flag is set the same as the sign flag. It has opcodes $2b and $0b.

There may be other missing illegal opcodes as well; but I don't know that.
