A workbench for developing 6502 code

6502 Emulator

🤓🕹💾 This hobby project contains software implementations of old microprocessors and complete computer systems. I'm very interested in retrocomputing and this is how I learn about the inner workings of these old, classic and amazing computers and game consoles.

SYSMON65 is a full 2-pass assembler, with local and global labels, directives, and more. A 65C02 disassembler is included which includes Step-By-Step debugging (i.e., Tracing), memory dump, ASCII dump, fill, delete, block move, intel hex loader and more.
