I use tougher monsters to keep the game fun after it has gotten too easy. (Unfortunately, MM8 is still too easy for my tastes, even with this file and a bunch of self-imposed rules.) Insert this monsters.txt file into your EnglishT.lod file, using the MM8 Level Editor. Remember to backup your EnglishT.lod file first. (This likely won't work on non-English versions of the game.)
The changes are simple: Monsters' hit points are doubled, and they are worth double the experience points. Also, they give slightly better treasure (in most cases, one level better, and probability increased by 5%).
I have adapted my MM7 skill editor for MM8. This is a barely tested beta version. It will load the MM8 skill progression table from the mm8.exe file or from a standalone file, allow you to view or edit the table if you wish, and can save the results back to the mm7.exe file or a standalone file.
The practical upshot of this is that you can change which skills are available to which classes (promoted and unpromoted). It does not change the skills initially offered by the "New Game" screen.
You may download the necessary files in .zip format or individually below. Before you start to use the program, read the help file and BACK UP your MM8.exe file. The zipped archive contains the following:
WARNING: If you install Greyface's patch, you must immediately delete your ski8edit.ini file (if you have one) before you use this editor again. (If you have the Greyface patch, and haven't used this editor yet, you can ignore this paragraph.) Failure to do so will corrupt your mm8.exe file. (If you've already corrupted it, reapply the patch. And delete ski8edit.ini.) The next time you run Ski8Edit, you will get a new, safe ski8edit.ini file. Do not delete this new one.
This program is freeware, so use it at your own risk. I have only my own machine and my own copy of MM8 to test it on, and cannot be held responsible for its behavior on a different computer, nor in the hands of a user who cannot follow instructions.
Enjoy your game!
