From c0dc8f9d2567bd2a7f0bbd0bf4a5f42194bbb102 Mon Sep 17 00:00:00 2001 From: Morph <39850852+Morph1984@users.noreply.github.com> Date: Sun, 5 Jul 2020 06:26:07 -0400 Subject: [PATCH] AM/ISelfController: Stub CreateManagedDisplaySeparableLayer Stub this by sending 1 layer id instead of 2 as yuzu does not support multiple layers per display.
