I could've sworn that I already did (and was stressing out because I couldn't remember my password, lol), but I just created a DSiWorld account. :)I wouldn't be surprised if the calculator works on O2DS. If it doesn't, it would be cool xD. There is also the DSiWare called Calculator for $2
IDK what all you were able to finish out of all of those things that you mentioned, but an O2DS compatible scientific calculator certainly sounds pretty cool to me! :)

it would be cool to see something like a Game Boy emulator for trying to push the browser to it`s limit, though Im doubtful that something like that is possible, but if so then we can play games without homebrewI think that would be illegal because it may have copyrighted games assuming its even possible. No audio, copyright BS, and more. Now, if there was a way to have a cool gameboy color like game, it would be cool though :D
