REDRIVER2 (Reverse-Engineered Driver 2)

PC (Windows and Linux): Build status

REDRIVER2 running on Windows

Timeline:

  • Feb 19, 2019 - created skeleton, one year long preparations
  • Mar 28, 2020 - started work on reimplementing the game, game intro running
  • Sep 19, 2020 - reimplementing game complete - game is fully playable
  • Jan 15, 2021 - refactoring complete

Information

  • Game was completely disassembled and reverse-engineered from MIPS back to C (except Memory Card menu overlay)
  • Game has been significantly improved over the original Playstation version, original bugs was fixed and completed some unfinished gameplay aspects
  • Utilizes Psy-X (Psy-Cross) (formely extended TOMB5 emulator) as a layer for porting from Playstation
  • Runs on Windows, Linux and soon to be on the other platforms (including backport to Playstation), no emulation involved
  • Basic modding support - with textures and models replacement provided with OpenDriver2Tools

What to expect from it

  • OpenDriver2 project - complete rewrite with lots of new features such as new renderer and sound engine, Lua scripting, Driver 1 content support

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)

How to use
