yeah totally because i want to know what the dsi looks like and sounds but my mom wont get me one but that would be cool because a dsi menu from dsi on 3ds so cool you should do it! and i will help you just create a play journal and we can talk about it and by the way im not that good at programming :]

You could create a DSi-like menu, yeah, but you couldn't make an emulator or anything like that. :P
