PSP game info questions

I have a PSP 2000 5.0 M33-4.
I a few PSX games on my PSP but I want to put PS2 games. Is that possible?
To unbrick my PSP I used the Pandora battery and Magic Stick.If am able to play PS2 games on my PSP what do I do?
Do I do the same process as putting a PSX game on my PSP?Another thing:
Can I play GBA and NDS games on my PSP. I heard you could, but Im not sure.
If so what do I need and what do I have to do?Thanks for reading and please leave a comment/reply or something.
I appreciate it. :)

I dont think you can play ps2 games on your psp, the psp simply does no have enough power to handle those games

ok yes to gba games i believe there are several emulators and SP kai is rumored to work with 100% functionality and a big no to the ds games i am sure it could be possible but the complete lack of a touchscreen or even mouse makes it implausable. as to a ps2 game it is pretty much the same as why the ds cant emulate the 64, it is just not possible to emulate a game system on another game system with nearly the same specs. plus i think ps2 games can take up to a full 8 gb dvd rom and i dont believe that a modded psp can use a memory stick over 4gb to load games from. hope this all helps

There's a topic on PSP emulators in the Trading Station.

cab9541 · #3i dont believe that a modded psp can use a memory stick over 4gb to load games from.

Official cards over 4GB work fine. I use two 8GB cards.PS2 won't work, GBA there is stuff for that. DS would just be too difficult due to the nature of the two screens and touch compatibility. I think someone worked on a DS emulator on PSP just to be shown it can be done though.

Yes it was DesMume. Since it's open source.
