Kingdom Hearts 1.5 HD Remix [BLUS31212]

I have found a semi-solution to the black screen after the final cutscene:

Thanks to the user Puremin0rez here: https://github.com/RPCS3/rpcs3/issues/6945

changing the END movie file allows you to skip the credits scene, which if you seen it once that's not a terrible work around imo, this allowed me to unlock the trophies I was after and see my end game stats

I renamed my file here \PS3\Kingdom Hearts - HD 1.5 ReMIX (USA) (En,Fr,Es)\PS3_GAME\USRDIR\KH1Movie\en called END.pam to tEND.pam

I believe EXM.pam is the "extra movie" so you can change that to whatever I just changed mine to tEXM.pam and I was able to get through Proud Mode as well
