 # MOS6502
 
-This is a toy project where I've created an assembler for the 6502 assembly language. An emulator is in the works and a dissasembler would be fun to do as well.
+This is a toy project where I've created an emulator, assembler and a dissasembler for the 1975 8-bit MOS 6502 CPU.
 
+The emulator takes either assembly code that the assembler transforms to machine code or native machine code directly which then the emulator executes.
