reverssg

The goal of this project is to create a decompilation of Super Solvers: Gizmos & Gadgets! that can ideally be recompiled.

Knowledge gained here forms the basis of ssgesus, my speedrun route planner for the game.

• Disassembled: https://delan.github.io/reverssg/1.2/ssgwin32.exe/ssgwin32.exe.html#00414750
• Decompiled: https://github.com/delan/reverssg/blob/default/1.2/ssgwin32.exe/annotated.c

how the sausage is made

• Ghidra 10.4
• ssgwin32.exe 1.2 https://archive.org/details/SSGCD
• analyse as borlandcpp (somewhat better than borlanddelphi)
• export Ghidra Zip File, default options
• export HTML, default options
• export C/C++, Create Header File on, Function Tags = annotated
  • Function Tags Excluded on → ssgwin32.exe{.c,.h}
  • Function Tags Excluded off → annotated{.c,.h}

patterns to look out for

• (T)(&x)[y] may mean x needs retyping as array
• CONCAT22(...) may mean undefined4 needs retyping as undefined2
• erroneous __fastcall (edit signature, change to __stdcall or __cdecl, remove first three arguments)
  • extraout_{CL,DL,CX,DX,ECX,EDX} may mean erroneous __fastcall
  • three or more arguments may mean erroneous __fastcall
