Keen: Modding

I have created two different versions of the requested patch. In the first version, two messages are shown after rescuing a Member, like in the original game. (The first with the picture of the Council Member and the second with the picture of Keen.) The value of $07 in the first line of the patch i...

I will certainly help you with the new patches, but it would be helpful if you could answer a few questions. 1. I assume the patches would be used in the same mod as these: Dopefish stun and win game . Could you please confirm this? 2. Do you want to use a replacement for the wetsuit in your mod? Th...

I updated the Schoolfish patches, the stunned creature is now affected by gravity. You need to replace all Schoolfish-related patches with the new ones. To avoid problems with the stunned sprite, I had to change the clipping from "full" to "normal". If this causes any unwanted si...

I have finished the Inchworm and Schoolfish patches. I used the "smoke" sprites for the stunned creatures because the Inchworm spawning code automatically caches them (originally for the 12 Inchworms spawn a Foot animation). I added a patch for caching the same sprites when a Schoolfish is...

I have finished the patches you have requested. Some notes about the patches: The following sprites are used for the new sprite behavior: 4SPR0282 and 4SPR0296 (ModKeen names) are the "flashed" sprites, which are shown temporarily if a bullet hits the enemy. 4SPR0283 is used for the dead c...

Interesting ideas, I will certainly implement this, but I need some additional information. First, do you want to use the "eating" behavior of the creature? The Dopefish has no "dead" sprite, so a sprite from the original game must be "sacrificed" for it (e.g. eating Do...

I was able to patch the Treasure Eater to open gem doors. As you have suggested, patching the Eater for this behavior was significantly easier as its code already contains a loop for checking properties of "nearby" tiles, which I could re-use for gem sockets. My patches: # Patches for Trea...

The menu color values (background color, highlighted and non-highlighted text) are used at several locations in the code. Apparently, some of them are missing from the Patches section of KeenWiki (I assume that you have collected the patches from there.) With the help of K1n9_Duk3's excellent source...

I was able to decompress KEEN1.EXE from version 1.34 with it under DosBox.

The patch you have posted modifies an instruction in the code which assigns a value to a variable at offset $6C62 in the data segment. The value of this variable affects the animation speed of tiles and as you have mentioned, animations in the high scores menu, title screen animation, etc. It does n...

Dear Dave216, Some of the patches you have requested: Sparky killed by 3 shots: Note: $0003w in the first row is the health # Sparky spawn, for setting "health" to 3 %patch $1102F $58 $8B $1E $9E40w $C7 $07 $0009w $C7 $47 $40 $0003w $BB $00 $FF $0E $E8 $000Fw $B8 $1F0Cw $50 $53 $9A $090B11...
