/* Finding these Addresses:
	Loading: Only "1" when the *smaller* loading icon is visible during true definitive loading scenarios. CE Access info = offset +98, 1count per load
		Seems like this pointer ends up actually being +A8 rather than +98, which happens sometimes, still a very close guess by CE.
	BLoading: 0=Playable, 1=BigLoadIconShown(usually)+More, 2=(sometimes)Cutscene+NewDialog+RespawnPosterBlkScreen. CE Access info =  offset +A0, always counting
	Easier to find BLoading through 4-Byte scans instead of 1-Byte as there are much fewer results, but Loading requires 1-Byte.
	Set up a hotkey in CE/Cheat Engine for "Pause the selected process" so you have time to scan at the correct times. Spamming this may crash the game.

	Downpatching to older versions like 1.0.386 involves downloading 2 separate manifests/depots:
	-app 1266700 -depot 1266701 -manifest 2948332448179647033 (Put in a new empty folder)
	-app 1266700 -depot 1266702 -manifest 4680887896957793053 (*Properly* place these files within the above folder)
	Launch with DH.exe
