Hard Drivin' source code...

[geneb]

While going through the 5.25" media in the vintage computer collection I got a few years ago, I ran across 5 unlabeled 5.25" disks, all stuffed into a single sleeve.

The contents appeared to be the complete source code for the Atari ST version of "Hard Drivin'".

 

The disks can be found here: https://archive.org/details/game-source-atari-st-hard-drivin

 

If anyone knows the author (Juergen Friedrich), please point them at that link.  I'm sure they'd love to see that code again.

 

Thanks folks.

Not sure all the code is for the ST, the .ASM files are not 68000, they may be Intel assembler

and PROTO.H does say

"LANGUAGE.............    Turbo C 2.0 for the IBM PC"

 

Maybe he was creating a cross system compile as STRUCT.H says

"LANGUAGE.............    Turbo C 1.0 for the Atari ST"

I was guessing at the target based on a few of the source files I looked at.  When you're hard pressed for time and imaging hundreds of disks, mistakes get made.

Hey, thanks for the archives! I'll have a try at compiling them using Turbo C just to see what happens. It might be that any missing assembly bits could be extracted from the released binary and the rest would match.

 

Anyway, thanks!

I see that some  .ASM functions are called from IBM.C

Hello,

 

Has anyone played around with the sources so far?

[geneb]

Not that I'm aware of. 

 

BTW, for those curious, the disks were sent to The Strong Museum of Play last week - that's the destination for all the Atari ephemera, etc. that I've been archiving.

I'm just commenting here to let you know that I've just made the C sources compilable on Linux.

 

Be warned. Compilable DOES NOT MEAN usable. The only use for this code, or at least my goal, is to be used as a base for a SDL2 for PC.

Maybe some talented coders here will find it useful.

Hmm, from a quick look I'd say this is original Atari ST sources already adapted to IBM PC, with any m68k files removed. Some files are missing even for x86, like screen handling.

 

Watching your project with interest.

Yes, this source code is for the DOS version.

What is there is working (interface, physics, sound)

but the whole gfx part is missing.

That's one segment but by far the largest code segment in this game.
Code has self modifying fragments which confuses disassembler
so you really have to comb through it manually to make sense of it.
If you were to disregard unnecessary functions, like CGA/Tandy routines,
this missing segment appears to be roughly 1/3 of the program.
