Verilog source code for a fully functional 6502 compatible cpu core. Experimental Core - 32 bit bus interface 6502 The RTF65002 Project a 32 bit cpu with 65C02 emulation Software Here is a 6502 macro assembler. It supports all the original 6502 instructions plus W65C02 instructions and is TASS compatible. It can produce a binary or S19 record compatible output. It's just called "asm" for lack of a better moniker. Experimental is a 65816 assembler also included. Source code for the assembler is now available on GitHub. (Cores\FAL6567\trunk\software\asm) asm.zip (about 350k)
