PS3 PSX games not running

[jimraynor30]

Hi! I've got a PS3 Slim (CECH-2012A) running CFW 4.91.2 Evilnat Cobra 8.5 [PEX] [noBD] (the BD is completely dead, I suspect a faulty motherboard connection).
I can't run PS3 games in ISO format, but I managed to install them alright in pkg format. However, when it comes to PSX games, it's not just bin files that fail to load, but also if I install them in pkg, they install alright but when I try launching the games, all I get is a black screen.
Is this a known issue? Is there any workaround?
Any help will be welcome! Thanks!

the bd drive needs to be connected in order to run any app on ps3. if the drive is disconected. the result of running any app will be black screen.

But that is not the case for the PS3 games (or homebrew apps) that I installed, they run just fine. Isn't there any way for PSX games to work as well?
