 Project attempting to reverse-engineer PS1 game Driver 2;
 
 ### Goals
-- Rebuild all of source code from assembly. 
+- Rebuild all source code from assembly
-- Compile it NATIVELY for **PC** (and probably **PSX** later)
+- Compile native version for **PC** (and for **PSX** later)
-- Make game playeble from start to finish, all game modes
+- 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 done
+### 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
+- 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. Copy DRIVER2 folder from your **game CD** to location where compiled EXE is located.
