PS3 Black screen when playing PSP games on CFW

[Windows10User]

Every time I run a PSP game I have a black screen after clicking on the XMB icon after mounting the ISO with multiMAN and running the game with different PSP Launchers. I only tested supposedly playable games according to the PSP Emulator Compatibility List but I still have this problem. I'm on Rebug REX 4.84.2. I can't use webMAN MOD/sMAN since it always freezes my PS3.

what game?

what game?

All supposedly playable games via a PSP Launcher from PSP Emulator Compatibility List. Does that mean that I shouldn't use PSP Launchers but always convert the PSP games to PKG (the ones which work that way)?

EDIT: Weird, now I tried playing the games with PSP Remasters Launcher and it worked.
