Is there an Nintendo DS emulator for a PSP?

In fact there is a beta version of DSONPSP that can be downloaded from the link below.

It works with some DS games. I have tried a few games and these are the ones that were playable; "Kirby Squeak Squad" and "Yoshi's Island DS". On the link below I have provided the emulator with both of the games. Just unzip the file and put it on the game folder of the PSP.
