Are new PSP 3 games backward-compatible with the PSP 2

psp

I was talking to someone who wanted to sell his used PSP-2000 model. He told me that whatever games are played on the PSP-3000 can also be played on the PSP-2000. I wasn't so sure about this so wanted to confirm. I did some Googling and noticed that wherever they mention PSP games they don't mention compatibility with PSP-2000 or PSP-3000, so here are my questions:

  1. Does anyone know whether ALL PSP-3000 games can also be played on PSP-2000? If not, how can I find out?
  2. What are the drawbacks of the PSP-2000 versus the 3000?

From this Gamespot article

The PSP-3000 plays the same games and offers the same media support as the older PSP models

So all the games are backwards compatible.

From Wikipedia

the PSP-3000 ... has an improved LCD screen with an increased color range, five times the contrast ratio, half the pixel response time to reduce ghosting and blurring effects, a new sub-pixel structure, a microphone, a new disc tray design, new button designs and logos, and anti-reflective technology to improve outdoor playability. It can also output all games by component or composite using the video out cable.[77]

So it's better. The biggest improvements seem to be the reduced ghosting (which still exists but is well, reduced) and the anti-reflective technology.
