A minor patch for Keen Day: Global game speed

Post by NY00123 »

Edit for Mort Day (:O): Well, now that Keen Day is over and I know at least one individual has tried this... I'd reveal what is the patch all about.
I've also removed the link to the little mod. If you're interested in it, you can follow the instructions below (in the original post).

Basically, the patch, intended for Commander Keen 4-6 and Bio Menace, lets one change the game speed globally.

For details about the patches, refer to these links:
http://www.shikadi.net/keenwiki/Patch:Game_Speed - For Commander Keen 4-6 (any other patch hasn't been added by me)
http://www.shikadi.net/moddingwiki/Patc ... nace/Speed - For Bio Menace

Edit: Lets make things simpler for now. Just download the following, extract to somewhere, and then run PLAY.BAT from within DOSBox :D
<Link removed>

As hinted before, it's not a big deal. But, at least some thing for today...

A little note: The link is to be removed soon (along with the file). Ones would see why by then, or so I guess...

Hey there,

As it's Keen Day now (March 14th, 2012, 0:00, GMT+2 time), I've thought of giving out an example of a small present...

Before I reveal more details, I'd like the ones interested to try out the following:
1. To begin with, have a clean installation of Commander Keen 4, Apogee release, EGA, v1.4. Just in case one hasn't got it, a download link is currently available in the following page: http://www.3drealms.com/keen4/index.html
2. Now, if you haven't got CK4PATCH, look for the most recent unofficial extension to CKPATCH here: http://keenmodding.org/viewtopic.php?t=975
Basically, you'd want this: http://www.0x27.com/downloads/ckpatch-0.11.0.zip
3. Even if you have got CKPATCH, there are chances you might still need to obtain a different version, in case you get an error with what's to follow. The above one is known to work.
4. Within the same directory, create a new file named PATCH4.PAT, with the following contents
5. Now you can run "CK4PATCH PATCH4.PAT" within DOSBox. Begin a game so you can see...

Code: Select all

# Patch file for Keen - use with CK4PATCH.EXE

%ext ck4
%version 1.4

%patch $18E79 $02BCW
%patch $18E7E $00AFW

%end
Now, if one wonders what has brought me to this... (not exactly a spoiler...)
Well, some of you may be aware of the IMF format used for in-game music. Ones may also know that a few so-called IMF rates are used, like 560Hz in Commander Keen and 700Hz in Wolfenstein 3D.
So, I've wondered if that speed can be changed in Commander Keen and/or Bio Menace...

Oh yeah: I'm going to reveal what's that soon. A few of you have possibly found the patch on the KeenWiki (for Commander Keen) or the ModdingWiki (for Bio Menace) before. That's all I'd tell for now... ;)

So I've had a thought which, eventually, leads to something similar to this (also posted today):

That explains why I've just updated the original post so it has a ready-to-play package. Not a lot to see, but one can still check it out.
