How do I use unlump.exe?
From OHRRPGCE-Wiki
Drag & Drop[edit]
Drag your RPG file and drop it on UNLUMP. If there is a password, you will be prompted to type it.
Command-Line[edit]
Open a Command Prompt (DOS window) Use the change directory command (CD) to navigate to wherever you keep the OHR:
c:\Documents and Settings\John> cd \ohrrpgce
Then type unlump.exe and just after your game file name (see below). Then enter the password. (Note that you are you going to see stars as you key in)
c:\ohrrpgce> unlump.exe mygame.rpg (password line)
Advanced uses[edit]
UNLUMP can unlump any lumped file, not just RPGs. HS and NEW files are also lumped, but at the moment that's about it.
