 PSX: pending
 
Project attempting to reverse-engineer PS1 game Driver 2;

Start Date: 28 March 2019

### Goals
- Rebuild all source code from assembly
- Compile native version for **PC** (and for **PSX** later)
- Make game playable from start to finish, all game modes should function properly
- Fix all reverse-engineering **bugs**
- 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.
