 5. **Do I really need to install this TombATI patch? Why not have just the .exe?**
 
-    One of our goals is to eventually provide a single .exe file (maybe with
-    some .dll-s related to multimedia) and only require the players to supply
-    the game data, i.e. the level files, music and FMVs. However, this requires
-    decompiling GFX and SFX routines which, again, is going to take a while.
+    We're currently on it! :D
 
 ## Current road map
 
+Note: this section may be subject to change.
+
 - [x] Reverse engineer the entire game - done!
 - [ ] Break off TombATI, ship our own .EXE rather than a .DLL
     - [x] Integrate glrage with Tomb1Main
