*	SH 0rigins IGT Display v1.02 (19/11/2023)
*	GitHub: https://github.com/BoredOfSpeedruns/Silent-Hill-0rigins-Autosplitter
*	Currently supports:
*		PPSSPP: 64-bit executable, v1.4-v1.14.1 and v1.15-v1.16.6
*		Game: US [ULUS10285], JP [ULJM05281], EU [ULES00869]
*	Contributors:
*		Parik: Emulator version detection via signature scanning
*	Notes:
*		- (optional) Install ASLVarViewer [https://github.com/hawkerm/LiveSplit.ASLVarViewer] & LiveSplit [https://github.com/LiveSplit/LiveSplit]
*		- It is advised to have PPSSPP and the game running before opening LiveSplit
