# mNES
NES emulator in mIRCscript

this is a learning experience for me. Figuring things out as I go. I don't know what I'm doing, please keep that in mind if you read the source.

only 51 opcodes are (probably poorly) emulated so far, don't expect much to run (yet), but feel free to look around and give me feedback ^-^

# how to use:

put a folder named ROMs in the same directory as all the files, and put a valid NES rom there.
currently, it just picks the first file it finds in there.

then you can load the script(s) with `/load -rs path\to\core.mrc`, followed by `/nes.init` to run it. It will not show (much) output by default.
if you want the pretty CPU output (about the only interesting thing to look at currently), `/nes.init full` will accomplish that, or `/nes.init error` if you (mostly) just want to show errors.

You can also manually turn on the output while the emulator runs by typing `/hadd nes.cpu debug full`, or you can set it to `error` to only show output when an error occurs. You can manipulate the status registers (`nes.cpu status.xxxxx`), accumulator, x, y, program counter, and so on the same way, if you like.

`/nes.init` will always cleanly start the emulator, `/nes.cpu.start [n]` will start the emulator from the last known state, where `n` is the amount of miliseconds to wait between each cpu cycle. `/nes.cpu.stop` will stop the emulator (and is (or should be) automatically triggered when an error occurs).

Somewhat compatible with Adiirc
