A bare-bones 6502 assembler and emulator in the Godot game engine

GD6502

A (currently) bare-bones, stripped down 6502 emulator and assembler. Currently, I'm using the 6502asm.com and the Easy 6502 emulators as goal posts to test GD6502's usefulness. After it's fully compatible with those two emulators, I'll start working on making it compatible with more complex 6502-based systems like the Atari 2600, NES, and others. At that point, I'll start turning it from a standalone project into a library to be integrated into other projects.

Examples

• The examples in ./examples/6502asm/ come from http://6502asm.com/ and credit goes to their original authors.
• The examples in ./examples/otherasm/ are for general assembler testing and may or may not be moved to the unit testing directory.

Tests

There are unit tests in ./tests/ that can be executed using Gut. To use it, run godot --debug-collisions -gexit --path $PWD -d -s addons/gut/gut_cmdln.gd

-gexit is optional here, and will cause GUT to exit after all the tests are complete. As an alternative, you can use -gexit_on_success which will cause it to only exit if all of the unit tests succeed.

See https://github.com/bitwes/Gut/wiki/Command-Line for more info on Gut unit tests from the command line.
