BoneCruncher Maps

I dug around in various games yesterday, looking for map/level data. Ravenskull looked promising, but I couldn't put a UEF file back together to play with, Thrust looks like it unscrambles its code and data when it loads, and I couldn't even face modifying Quest.

BoneCruncher (or is it Bonecruncher?) was a lot easier to figure out, so I adapted my Repton/Repton 2 editor to cope with the different sprites and level sizes. The code can be found in a repository on Bitbucket. See the attached image for a screenshot.

I didn't track down where the passwords were stored, and I note that the first set of levels in the "SCREEN 1" file is a duplicate of the ones stored in the main game executable, presumably to be reloaded after another set of levels has been played. Personally, I never got that far, so I don't actually know what the game does after level six.

BoneCruncher may not have been as popular as the Repton series over the years, but if you've always wanted to design your own levels then now you can. :D

Looks great! Agree that Bone Cruncher was somewhat overlooked as being a Repton clone. I thought about doing a level editor when i created the maps way back when after borrowing the code design from a BBC BASIC program that created redefined character based maps but alas I don't have the necessary time/patience to create.

Thanks! The trouble with these editors is knowing what to do with them once they're written. I'm not inspired to create a new set of Bone Cruncher levels at the moment; even less so with the Repton games! :)

I noticed that the STH maps were yours. Did you take screenshots or were they created by decoding the level files?

Decoding the level files using a BBC BASIC for Windows program, with each object saved as a BMP and the level files saved off as data files that could be read from Windows. :)

Good work, there! :) I used those maps to help figure out the format.

I've now written up some of the details of the first two Repton games and Bone Cruncher on the Retro Software Wiki. I looked at Icarus, too, but only managed to extract the map data, so there's no graphical editor for that yet. :D

That's ace, top piece of work there!

Thanks! I've hopefully exhausted my obsession with remapping old games for the time being. :D
