I'm not one for self-promotion, but I thought this might be worth putting out here.
I'm working on a website called DSi World, which you can find here. There's not much there as of yet since I'm still learning the ropes on how the Nintendo DSi browser works, but I hope to expand this site into something bigger.
I'm planning on adding utility stuff there for the most part, such as a DSi-compatible email client, a MangaPanda reader, and a Git client. If there's anything more you'd want to see, please let me know, either here or in a DM.
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. :)
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 homebrew
When life gives you, wait what does luigi taste like?
