I'm almost ashamed to ask...

But can someone guide me through making a patch file for a Keen-1 mod?

It's pretty simple. You don't need to know what any of the codes mean (usually), just how to copy and paste them.

First make sure you have a copy of ck1patch.exe in your mod's folder,

1. Make a plain text file:

Code: Select all

ck1patch [patchfile].pat

You can replace the "[patchfile]" with anything you want. Something like "patch.pat" or "yourmodname.pat"
And save it as "run.bat" or something similar. Just make sure the extension is ".bat".

2. Make another plain text file:

Code: Select all

%ext ck1

%end

And save it as [patchfile].pat (make sure the name matches the one in the .bat file.

3. Add patches. They go in the space in-between the two lines in the patch file.
Find a patch on Keen:Modding or at http://levellord.rewound.net/Index/
So say you want this patch:

Code: Select all

#Set ammo to 0 after exiting each level
%patch $4F43 $31 $C0 $A3 $9E $AA $A3 $A0 $AA $A3 $A2 $AA 
             $A3 $A4 $AA $A3 $9A $AA $A3 $C8 $AA $90 $90 
             $90 $90 $90 $90 $90

This patch, as it says, will make Keen's ammo go to 0 after each level.
You would copy the patch into the patchfile.
So your resulting patchfile would look something like this:

Code: Select all

%ext ck1

#Set ammo to 0 after exiting each level
%patch $4F43 $31 $C0 $A3 $9E $AA $A3 $A0 $AA $A3 $A2 $AA 
             $A3 $A4 $AA $A3 $9A $AA $A3 $C8 $AA $90 $90 
             $90 $90 $90 $90 $90

%end

Now you can save the file, run your .bat file, and the game should run with the patch.

Hope I explained that well.

To add, for some of the easier patches, I'd recommend you download theneuralstunner by Mink (here: http://keenmodding.org/viewtopic.php?t=1134&start=0), and use that for making your patchfile.

If you want wacky patches, add a command like this:

%patch $[randomnumber] $[random 2digit] $[random 2digit]

Indeed, after the firs 500 tries, you may come across something that doesn't crash the game!
