Duplicate of this and this one as well ~ should all be merged.

You can pass the blackscreen by simply pressing buttons in correct order as you would if menus had graphics so it actually goes in-game.

Either way this is a known depth problem ~ replicating psp depth on modern gpu's isn't exactly easy, so bothersome games which depend on exact depth might not get a fix for a while.
It's totally different story when it comes to cpu, so if you're desperate you might use software rendering(can only be activated before running the game ~ it's on the bottom of graphics settings menu). Expect it to be slow and glitchy in different ways through.
