Boulder Dash custom caves -> executable

[_Fandal_]

Hi all!

 

I spent a lot of time with Boulder Dash Construction Kit as a child and I always wonder how to create executable file with my own caves. Is there any tool or all those file versions flying around (e.g. Bandit Boulderdash XY) were done "by hand"?

 

Thanks a lot for any help!

For those who care: I wrote simple PC DOS utility for creating A8 standalone executable binary from BD Kit "CAV" and "INT" data files.

 

Many many thanks for help to Homesoft!!

Great, thanks a lot!

 

Could you post some details about the EXE/cave structure and/or the source?

 

so long,

OK. More details. My utility uses BD engine compiled by Homesoft which is able to handle up to 47 levels. Number of caves is stored in the last byte of engine data block. The first cave is strored at memory address $60F0, the second one on $62F0, the third one on $64F0 and so on. I don't have any source of engine itself, I just received compiled binary and instructions how to use. All my work was to write that short PC DOS program.

cool Fandal, I'll check this out tomorrow. I've just been finishing off the bd2 revamp this week.

Fantastic! Fandal & Homesoft

 

Now I can dust off my levels and release them to the world

 

Hey Fandal is there any way 'the community' can support you more - e.g. subscribing to zong magazine or something really appreciate the work you put in for our beloved 8-bit machines

Wonderful, thanks a lot!

 

I just had a quick look at it, and on the output of bd.exe:

 

engine.dat is a single COM block without the $FF,$FF header, loading to $3000-$6042. $6042 then contains the number of levels.

 

bd.exe also adds a RUN block at the end, with address $5bb5.

 

Great, this is all I need to finally build a standalone EXE with the levels I created in the late 80s together with a friend :-)

 

so long & thanks again,

Hi,

 

Here there is an executable with some brand new levels created by Doctor Mugen

 

I hope you like them.
