Would Like Location Of Original PDB (symbol file) Mentioned In The Readme

[KeplerIO]

Would be VERY interested in seeing the orignal PDB or symbol file otherwise that was mentioned in the README. Is this still available?

The original PDB file is yet to be uncovered (i.e. C:\Diablo\Direct\WinRel\Diablo.pdb associated with the debug release of Diablo 1, version 1.0). To the best of my knowledge, this file has never been seen in the wild.

The symbol files however, have been seen in the wild. More specifically, the symbol file diabpsx.sym is present on the Japanese Playstation 1 releases of Diablo 1. The debug information recovered from some of these symbol files is listed at https://github.com/diasurgical/scalpel/tree/master/psx

For instance, the earliest know version of the PSX symbol information is part of the ID 3 release: https://github.com/diasurgical/scalpel/tree/master/psx/_dump_/3/_dump_c_src_

Example of recovered debug information from monster.cpp:

https://github.com/diasurgical/scalpel/blob/2c32984ffe66eb34da22023d4ad2975a8abebeaa/psx/_dump_/3/_dump_c_src_/diabpsx/source/monster.cpp#L48

// address: 0x80140A40
// line start: 554
// line end:   576
void M_StartRAttack__Fiii(int i, int missile_type, int dam) {
    // register: 16
    register int md;
    // register: 2
    // size: 0x70
    register struct MonsterStruct *pmonster;
    // register: 3
    register int _mx;
    // register: 5
    register int _my;
}

And the associated type information: https://github.com/diasurgical/scalpel/blob/2c32984ffe66eb34da22023d4ad2975a8abebeaa/psx/_dump_/3/_dump_c_src_/types.h#L3313

The reason we are interested in the earlier psx symbol files is that the port diverged from the pc version (probably around 1.04) and does not appear to have kept up with later updates.

I see, thank you both for nice info! I love passion projects such as these.. Was thinking that since this is not the original actual code structure, we could rebuild original layout using these file. Maybe in time. I like the work you guys do on this. Can probably close this issue :)
