- As a consequence, a minor bug in the image loading routine has been spotted while originally implemented. Upon fixing it, though, it has resulted in a crash... Why? Well, on vanilla Keen the image is temporarily loaded to the map data (!!), but the fix wants to update the screen. This includes an...

I've got this. %ext ck1 %version 1.31 #pushy Garg turns into deadly butler when shot: %patch $184E $05 #Garg sprite type %patch $1BF5 $1DC7W #Dead Garg behavior %patch $1BFA $1E94W #Dead Garg collision %patch $1BF0 $0060W # Dead Garg sprite %patch $1BFC $C7 $44 $00 $0003W #instead of jumping when sh...

That's done in the level_init routine. As written you can easily change two of the sub-type numbers: %patch $1698 $0001W %patch $16A6 $0002W Type 0 is a special case, I think it would be necessary to to patch $168A to jump to a routine elsewhere. To change the sprite plane ids: %patch $1636 $09 #Typ...

Sorry about $20F6, $20FA is definitely what I meant to post. I'm not sure what you mean by cube type. I'm looking at the disassembly of the entire cube spawning routine, and there's no such thing. They are only given different initial velocities, after which they all execute the same code. If you me...

Basically, you've gone too far. The patch at $2102 is leaking into the first jump table target. Those values are offsets into the sprite structure (X position to be exact). Here's my take on that patch: #cube type %patch $20D6 $000FW #length of jump table %patch $20F6 $0003W #address of jump table %...

I'm on the case. It may take a while for me to get back up to speed, but I still have the assembly source, it shouldn't be too hard. The Status Menu 1. A bug I've run into, presumably with Dr. Kylstein's patch which tweaks the palette, is that when the player activates the status menu on the world m...
