okay... not 100% sure on the validity of this, but I found the following post... Code: Nintendo DS emulated on the PSP For all intents and purposes though, and right off the bat, we'd have to say that we can't host the download. One of the main reasons is that the emulator taps into the BIOS - thus leading to its illegality - and the second reason being its infantile stage. We hear the emulator isn't working all that perfect; running games ends up in lock ups and glitches. So right now, we'd just have to report about its existence, and for the sake of discussion, talk about the implications. One of the biggest hurdles here, of course, is that, how would a DS emulator work without the DS' biggest features: the touchscreen? The experience of getting to play the real Nintendo DS will be watered down in an emulated Nintendo DS on the PSP, but see, isn't that what emulators are defined as? We know you have a lot of questions, proclamations, and out bursts of joy. So we'll leave you with two options: 1) you may comment below, or 2) proceed to the forum thread for an in-depth discussion. However. Please bear in mind that we will not tolerate any links, information, or other details on where or how to get ROMs and illegal files. url here..... clicky what are your thoughts?
