Ermm... wouldn't restoring Embiggening lead to problems arising in Metal Gear Solid Portable Ops again? I remember you removed this embiggening function because it was the cause of all those flashing/flickering black screens in that game a long time ago.

See this https://github.com/hrydgard/ppsspp/commit/0abbf1efb7c5db7c9c98b682b6939ec0dd7804ae (the commit you proposed that removed the embigennings) and https://github.com/hrydgard/ppsspp/issues/2438?source=cc#issuecomment-21243839 (the issue caused by embiggenings)
