This is a 6502 emulator that I wrote back in the 90s and have been trying to clean up a bit. It is not complete but supports basic assembly, execution, and debugging. See the TODO file and the source for a full list of items needing to be completed.
The software builds on both Windows and MacOS. See the BUILDING file for instructions.
See the CHEATSHEET for usage instructions.
Warning: this program is under development and has only been lightly tested. The unit test set is quite incomplete.
