Berzerk new robot taunts

Post by scott_tunstall »

I've been reverse engineering Berzerk (http://seanriddle.com/berzerk.asm) and managed to work out how speech is generated.

As a result, I've created some new taunts for the robots - 14 of them, to be precise. I think they make the game more fun.

This will patch the COLOUR TEST code from $0200 onwards with new code to handle speech.

Apologies that all the instructions are byte-sized, not qword-sized which would have shrunk the size of the cheat considerably, but this is the best I could do with the time I had.

Code: Select all

Re: Berzerk new robot taunts

Here's the Z80 source for the cheat, if you want to add your own taunts. You can paste this direct into a Z80 project on ASM80 online to build. and produce the hex opcodes to make the cheat. The EQUs below are the unique IDs of the words that Berzerk supports.

If you create derivative works from this, a wee credit to me would be nice :wink:

Thanks, q-worded and made it into a standard format cheat. Quickly duped for the 5 clones, though I don't know what the french, german & spanish versions will be saying.

Duplicated using the following debugger find commands:-

;0200 = f 0,ffff,1,48,10,ed,78
;2baf = f 0,ffff,cd,?,?,e6,1f,f6,60
