Who?

What?

This is a very dumb MIPS to C static translator. Consider it a proof of concept, as it has successfully worked on at least one non-trivial program.

When?

From December 2013 to March 2014.

Where?

Tokyo.

How?

You will need a version of IDA that is not yet public. Whatever version comes after 6.5 should contain all the fixes that are needed to produce the code used in ElectroPortis.

The decompiler depends on these libraries:

• pycparser
• flufl.enum
• pyc-fmtstr-parser

The decompiler is not a push-button solution: some small annotations to the IDA database were needed to produce fully-working code. If you wish to use it on your own target, you will probably want to modify it to do data/bss segment extraction in a saner way. The easiest thing would probably be to just lift them out and treat them opaquely, i.e. as a char[], and then handle endianness issues accordingly.

Why?

People have wanted ElectroPaint (the real thing, not a clone) on something other than IRIX for longer than your author (of the decompiler) has been alive. Someone had to do it.

Python?

This was an experiment. The two options that did not require writing bindings for IDA were C++ and Python. I don't think I'll use Python again for personal projects in the future, and I should have written IDA bindings to a statically typed language (other than C++).
