Hey people... i just wanted to share this amazing project i ended up finding. It's from the same author of nodeNES...

pyNES allows you to write NES games in Python. It is a full 6502 ASM compiler, aiming to make the development of NES games easier and much more fun.

Cool!

I don't really understand the description. 'It is a full 6502 ASM compiler' means that it is a 6502 assembler written in Python, or a Python compiler that produces 6502 assembly code?

This has to be a fake, right ?

So now we can code NES programs in C, and also in Python? I'm interested in seeing how advanced the programs can be, as Python is a higher level language than C, so probably more complex to compile and more demanding of hardware resources. Also, seems it's using NESASM to assemble.

means that it is a 6502 assembler written in Python, or a Python compiler that produces 6502 assembly code?

The latter.

I don't see why it needs to be fake, especially if it only supports a small number of simple operations.

They say they have wiki but it doesn't seem to have anything on there.

Another idea could be Haskell Famicom Maker, which would be a Haskell library for making games compile into iNES binary, .NSF, UNIF, ASM, raw ROM binary, and whatever format. (DotFami HDL is like this, but for hardware instead of software.) Such thing however would not be a Haskell compiler it would be a set of mathematical operators to describe them, and functions to make them combined and optimize and whatever.

Other possibility too, such as make a BLISS compiler for 6502, or Pascal or BASIC or whatever other programming languages you want.

Very cool project!

It seems to have a small bug on directives.py on line 34: on my Windows 7 machine, python says that 'rw' is an invalid mode. Changing that to 'r+' fixed the problem for me.

Good work! I hope this leads to some interesting homebrews.

There is a computer game (called "Taking Over The World") written entirely in brainfuck actually. If it can be optimized and using ASCII set, together with a Famicom keyboard decoder into ASCII, then it might run on NES/Famicom too, but maybe slower, even if optimization is performed.

Hasn't someone on here already done that?

That's the point: the interpreter is there, we're just waiting for an awesome game that runs in it.

Very interesting project. Also on HN: http://news.ycombinator.com/item?id=4833860

Has anyone tried using it yet? I checked __init__ for command line info and it still doesn't output anything.

python mario.py -a asmfile.asm

In any case, I hope there's a way to insert asm into the python code (Not too clear on that, looks like you just have to read the compiler code to figure anything out), otherwise this won't be as exciting as it should be.
