Added Gfx wait on LoadMenuEnd(). Otherwise, some levels would not start after loading all required files.
Also, added GPU wait on Menu.c before entering the main loop.
An invalid index inside sound table was being accessed when creating an arrival flight. This made the game crash only under real hardware.
Other minor changes and fixes.
* Game.c: new prototypes GameGetParkingDirection() and GameGetRunwayDirection().
* Slight optimizations into GameRenderLevel().
* Added some comment headers into Gfx.c.
* Aircraft now prevents collision against other aircraft if state == STATE_TAXIING.
* Game: new event handlers for new Aircraft collision prevention algorithm.
* Font: although not compulsory, _blend_effect_lum should be volatile.
* Other minor changes.
* Sine-like effect used for runways now moved to SystemCalculateSine().
* Bugfix: ptrPlayer->FlightDataPage is now decreased if there aren't enough active aircraft.
* On main menu, 2 players option is now disabled if pad 2 is disconnected.
* More work on FPS measurement (not working yet).
* Number of used SPU voices is now returned on SfxUploadSound().
* Makefile now rebuilds needed targets on modified header files.
* Some more work on GameEmergencyMode().
* Initial work on PSX mouse auto detection.
* Prototypes for RCNT2 I_MASK bit handling.
* Files needed for Game are now only loaded once, except from LEVEL1.PLT.
* Added DevMenu to get debug info.
* ISR_LoadMenuVBlank() does not stop when accessing SIO.
* On fopen() and SERIAL_INTERFACE defined, "#" is prepended and "@" is appended to filename string.
* Removed obsolete, unused functions.
* Performance optimization: routines inside GameCalculations() were computating a big loop several times, so this has been modified so that loop is only performed once.
* Initial implementation for GameGetAircraftTilemap(). Still some work TODO.
* Remove unneeded whitespace character on pointer variables (unary operators should not have any whitespaces).
* SelectedAircraft index now increases or decreases automatically on aircraft added/removed.
* Started writing Plt generation routines. Still a lot of work TODO.
