yagsdisasm - Yet Another GS Disassembler
========================================

yagsdisasm is written in PHP, which may be an unfortunate choice of languages to many, but is nearly-universally available and makes for a product that's easy to modify, when written properly.

the disassembly engine is largely inspired by Andy McFadden's Ciderpress disassembly engine, which is why we copy his license terms in LICENSE.txt

as of 5/25/2016, the project is only a couple hours old and is a proof of concept. future revisions to come later
