How do you make a real PSN eboot play on any PSP with any account?

[XularusXIII]

So my friend has shared Dino Crisis and Resident Evil 2 with me, but I cannot use my Disgaea 2 DLC with my PSP activated using his account. So my question is, how do I make it where my PSP will play eboots regardless of whose account it's activated with?
The error I get when trying to boot the games with PRO-b10 CFW is as follows:

The game could not be started.

Oh yeah and, if it matters, I'm using a 2000.
