REDRIVER2

PC (Windows): Build status

Project attempting to reverse-engineer PS1 game Driver 2;

Goals

  • Rebuild all source code from assembly
  • Compile native version for PC (and for PSX later)
  • Make game playeble from start to finish, all game modes should function properly
  • Fix some existing critical bugs and performance issues
  • OpenDriver2? rewrite code, implement various cool stuff, PC rendering and audio engine, get rid of hard-coded stuff

How is it done?

  • All information (variables, types and function names) have been obtained from debugging symbols (.SYM), driver_psx_level and DLE
  • Ghidra project (based on Italian SYM) to deal with overlays, simple code complex branching - semi-auto decompilation
  • IDB based on Spanish SYM when dealing with things Ghidra can't handle properly - manual decompilation (mostly GTE code)

Usage

  • Assuming you have compiled the most recent code or got artifacts from Appveyor. Copy DRIVER2 folder from your game CD to location where compiled EXE is located.
