List of conversion offsets/formulae between game versions

This page is intended as a reference for address offsets and formulae for converting codes between different versions of a game (1.0, 1.1 on the same platform, or 1.0, 1.0 on different platforms, etc), so as to provide a centralized list. Without further explanation, I shall add a few. Feel free to contribute. Also, I (LB) have created a small app to carry out these conversions for you (Majestic Porter), which can be found in the Downloads section of GSHI. Hopefully, we'll implement the functions of Majestic Porter in an online app at some point, making them easily available to anyone without a download.
