Don Pedro and the Zombie Crackers
Posted: Sat Mar 28, 2009 11:40 pm
Well, i believe i played Boulder Dash for the first time at a friends house. I don't remember the year, it must have been in 1985. Soon afterward I got my own C64 and a tape copy of Boulder Dash I and II
I became an instant fan, my favorite cave in BD 1 was Cave I.

In BD 2 it was Cave L.

I didn't see myself as a very good player and over the years I haven't really improved my skills. But fortunately several of my friends back then (omg, it's almost 25 years ago!) were quite good players. We gathered every now and then after school and played until the joystick glowed.
My C64 assembler skill became better and with the help of some cartridge (forgot the name) I was able to freeze the game and have a look under the “hood”. Soon I found out where and how the caves were stored and starting building my own construction kit in Basic with a lot of peeks and pokes.
I made a couple of caves on a squared paper, but soon found out that I needed a lot more caves to make my own game. So I invited my friends and family to design the caves – we all then became the Zombie Crackers – although only a couple of guys had computer skills and none of us had ever cracked a game. We had a lot of fun and honestly never thought about giving the games to others, I mean they were not that much better than BD 1. But another guy I meet convinced me that he could trade these “homemade” Boulder Dash with new great games for the C64. In our BD 4 I changed the Boulder Dash start screen, added "Zombie Crackers" and gave him a copy on tape. The third guy in the chain phoned me some weeks later and was told me he was thrilled and asked for more, and that was how it all started.
Ten years later, when the Internet arrived, we found our games out there available for download. I was very surprised - I never thought that our home brewed stuff would make it beyond this third guy in the chain. I started asking some of my colleagues and new friends if they ever tried the Boulder Dash 4, 5, 6 or 7. Some of them answered yes, but when I told them that I was Don Pedro, not all believed me.
We actually started with Boulder Dash 4 – The one called “Masters Boulder Dash” by Zombie Crackers. BD 5 was the first with the intro screen which stamped it “Don Pedro” and from there we went on until BD 13.
EDIT: After Sleeping on it: I can't remember ever calling it "Masters Boulder Dash", maybe someone out there changed the name, because of Dr. Watsons BD 4.
Yeah, 13 is not a typo - back then we actually made BD 12 and 13, but somehow the C64 was already doomed and I was starting on Business College, so they never made it to the Internet. Some years later we found the tapes, but we had no C64 to load them anymore.
So how did we test them? Well, I must admit we just tested level one, which means that caves with random things could become unsolvable at higher levels. The unwritten rule was: If just one of us could get through level one it was finished.
What about the Construction Kit (CK), how did you do it? As I wrote above it was a Basic program. The levels were typed in as String Characters into variables. At run-time those were converted into the right values and poked into memory, quite simple. After finishing it on squared paper, each member looked it over and we all agreed in consensus if the cave should be in the game or not. Everyone took turns at the keyboard typing them in.
One thing which always disturbed me with my CK, was that I was only able to change the setup of the caves slightly, I was unable to add more objects than there already were. I don't know why I didn't spend more time trying to find out how to, but that explains why most cave setups across all our versions are almost the same.
I was happy enough to stumble across Arno's Great Fan-site Forum, so now you know the story about the Zombie Crackers and Don Pedro.
Cheers
Don
