This will be hacked unless its got security like the ps3. And an internal battery doesnt seem to prevent what an external battery might have been used for, you just open it up. if there has never been a psp mod chip they still have the option to use it if needed.
I always thought the system failed before piracy. Maybe the software developers couldnt get the margins they wanted but the hardware sales are something to boast about now. I thought the reason software wasnt doing well was because there were few quality games on the system even early in its life and it had to compete with gba and ds. Honestly I never heard anything good about the systems games (at least not much) in those times.
