I released a new version of Games::NES::Emulator. It still doesn't work. :) But, I'm getting closer. Ive added a bunch of the 6502 operations. My interpretation of their functionality may be, uh, well, off -- but I've added some debugging to see what the state of the emulator is after each instruction.

Eventually I'll do some disassembling and fix up the "Code" section to reflect the actual op names and params.
