Bless you child.
For your past good deed, I will respond to your topic.
There are many reasons why this won't work:
1) The specifications and hardware of the DS makes it impossible to emulate, let alone
run PSP and PS1 games.
The hardware of the DS is incredibly inferior to the PSP. Just comparing the core processors alone (67MHz of a DS compared to 222MHz [default clockspeed] of a PSP) would make the idea seem dumb.
2) Using Win2DS would be too laggy. Also, I don't think there's a working PSP emulator.
Fact is, laggy games aren't playable. This needs no elaboration.
3) Not enough buttons on the DS
You could use the touch screen to emulate the analog nub of a PSP, but good luck fitting in the rest of a DualShock's controls.
4) The damn screen resolution is too small.
DS: 256 x 192
PSP: 480 x 262
PS1: 320 x 240
This needs no further elaboration.
