Programming

I had some great progress on my Python 65c02 assembler project. I have all opcodes tested and can check if an instruction is valid. For instance, lda 30,y is not a valid instruction, while lda 30,x is valid. Now it’s up to me to test some instructions. 👨‍💻

A code editor is open on a device screen, displaying a table of instruction bytes on the left, and a Python script with a console output on the right. A code editor displays Python code on the left side for an instruction parser and a list of assembly-like instructions on the right side.
