I have attempted to debug Amplitude (2016), which also runs on Harmonix's Forge Engine.

The game shows the ESRB logo, but lands on a black screen when the intro video should play. Modding the game to not play the intro video still results in a black screen, which leads me to believe scenes aren't working.

Some important shaders fail to translate and I also saw flip rendering commands failing to validate.

The main shader that is responsible for drawing the UI scenes is most likely preventing the game from working at the moment.
Input is only meant to be processed once the shell animations have finished, so we can't even blindly navigate the game.

The game boots fine otherwise, as it seems to be in the regular engine loop on the black screen and does load in all the files that the particular scene needs/wants to preload, including songs.

v0.2.0 has the same result

xezrunner commented 3 months ago

My fixes for Amplitude (https://github.com/shadps4-emu/shadPS4/pull/499) get Rock Band 4 (specifically v1.0) to boot to the startup screen, according to a tester on Discord.

Requires further tinkering.

can confirm that these fixes do allow to get to the start screen, then a crash with 

[Debug] <Critical> liverpool.cpp:ProcessGraphics:459: Unreachable code!
Unknown PM4 type 3 opcode 0x20 with count 2

identical outcome for game version 1.08 with these fixes

game version 2.21 crashes instantly on v0.2.0 with or without the fixes

[Debug] <Critical> memory.cpp:operator():415: Assertion Failed!
