That's the licensing stuff out of the way.
sh2dis is a very rudimentary automated disassembly tool for SH2 processors written in Python. The internal representation and produced output are inspired somewhat by IDA Pro, a general-purpose multi-platform code analysis tool.
It can currently do relatively broad automated disassembly by tracking register assignments loosely and following branches where it can reasonably discern a destination. It doesn't catch everything yet, and likely never will; the end goal is not a full-on SH2 simulator.
The example command line tool, sh2dis, is capable of distinguishing between
SH7052 and SH7055 ROM formats, and will perform an automated disassembly around
the vector interupt table, labelling any known vectors and registers. This
example application may not work well with applications other than ROMs taken
from a Mitsubishi Lancer Evolution ECU, as that is the only platform I have
direct access to.
The easiest way to get started with sh2dis is to install it from PyPi. At a command line, assuming you have a working Python environment already set up, just run:
pip install sh2dis
From there, running sh2dis --help should be a good place to start.
This software likely contains bugs. If you find one, please open an issue.
Thanks for looking!
