Hello NGU, Phreaker here
Today I'm going to help fix black screen for any Game you get this black screen with
Here is how to fix the black screen on Resident Evil Revelations 2 or any other game you get black screen with when playing from Backup, Disc, Or PSN Version of the game on DEX
Go to Debug Setting and scroll down to where you see Boot Mode and change it to Release Mode
Down side to playing on Release Mode is you can not edit memory in real time with PS3 Debugger while in Release Mode it only works in System Software Mode, So if you want to real time edit this game you will have to use CCAPI on DEX.
To go back to System Software Mode just do the steps I just said but instead of Release Mode do System Software Mode to take your PS3 back to normal.
I hope i helped you guys if so please give thanks
