====== AV Mods ======

Most pre-NES consoles offered only [[http://en.wikipedia.org/wiki/Channel_3/4_output|RF]] output, and can be difficult to modify.  Almost every post-NES system had a wealth of video options, most offering at least [[composite video]] output, and many easily hacked to allow [[RGB]] output, and sometimes [[S-video]].  On this page you'll find the GameSX library of video hacks - some useful, some trivial, and some downright evil.  All, however, will grant you better quality images than you're seeing now.  

When [[http://wiki.dontpressstart.com/index.php?title=Lawrence|Lawrence]] started GameSX.com back in ~1996 there were no sources for this information online.  Gopher was still vying with the infant WWW as the most useful resource, and GameSX.com - originally intended to be a website for Game Station X (Lawrence's store) was instead a repository of knowledge gleaned from obscure sources and trial and error (mostly the latter).
