Supermodel/Src/OSD/SDL/Main.cpp

//TODO before release:
// - remove UI dump input state
// - VBL timing?
// - Controls for Dirt Devils, and other recent games (is bass working?)
// - Stereo reverse option (see Srally2 sound test menu)
// - Comment source code, clean up
// - BOOL -> bool, TRUE/FALSE -> true/false
// - Add option for building with /MD in MSVC Makefile
// - Remove SUPERMODEL_SOUND
// - EmulateSCSP -> EmulateSound ?
