Here's you something to look at. It sure caught my eye. Apparently, someone is attempting to make an x86 emulator for the DS. Something to play DOS and old DOS games. Details, copy/pasted because i'm lazy-
"Hi all!
For the last 4 months I have been working on an x86 emulator for NDS.
Now finally I have something to show for my efforts, so I decided to
announce this project, and release a technical demonstration.
DSx86 currently emulates 80286 processor, MCGA 320x200 screen and SoundBlaster audio.
You can find the demo at http://dsx86.patrickaalto.com/
The demo has my old DOS game LineWars II bundled with the emulator core. The emulator runs the game between 5 and 15 fps, with rare peaks up to 30 fps, depending on the amount of ships alive and visible on the screen.
I have also a blog/diary on my DSx86 web pages that gives some background about the emulator in case you are interested.
Thanks for reading!

Honestly, I'd like to see this happen, but most people will likely assume it's not possible to emulate an entire PC platform on a system like DS. Who knows though? Already better than that dosbox concept that ran at like 2fps.
