Gaming Having trouble playing two games

[Excellentnuke]

I tried playing Fate/Unlimited Codes and Tales of VS on my friend's PSP 3000 (I'm using his since mine broke and I'm waiting for replacement parts to come in) and neither of them work. They get past the Sony logo, but they hang at a black screen; however, I am able to press the Home button while stuck on this black screen.

Both games were downloaded pre-patched and I am using a clean ISO form.

Any ideas?

Change the driver.

That.
Some games only work on certain drivers, for example I tried running MotorStorm Arctic Edge on Sony NPblahblahblah and it got past the sony logo and gave me a black screen, the same as your problem. But when I switched to M33 driver it worked perfectly.

Press Select on the XMB menu to access the VSH menu, where you can change the driver.

You got to decrypt the eboot.bin and build your iso with umdgenv4 for it too work on yours and your friends psp.
And change drivers aswell.
