From OHRRPGCE-Wiki

RPGFIX is a tool designed to update an RPG file to the latest version without opening it in CUSTOM. It was important for older versions of the OHRRPGCE, but in current and future versions, the updating work is built into GAME.EXE. The only time you need to run it is when you see an "Obsolete RPG" warning when you open an old RPG file.

It is distributed together with LUMPFIX
