Kingdom Hearts 1.5 HD Remix [BLUS31212]

I have tried a few things to work around the black screen after the final cutscene which prevents me from 100%-ing the game; as described here: https://forums.rpcs3.net/thread-202026.h...dom+hearts

-Not skipping cutscenes after the final battle (this made no difference)
-Skipping cutscenes (doesn't seem to matter)
-different save files I have the one I played through all the game with and another one I found online, it didn't seem to matter though
-on page 4 of this thread a user jvanzalen describes some things that have worked for getting around the Atlantica/Jafar bugs I've tried both with this setting and without; found here: https://forums.rpcs3.net/thread-180504-p...dom+hearts
-I've used the cheat engine 60 FPS method (it made no difference)

I'm not sure if this is helpful to someone in resolving the issue, but I am done testing that for a bit today.

A new issue occurs with Proud Mode and the secret ending, as soon as I find the name of this movie file I'll see if changing it can work around this one as well, will update.
