This is an interactive demo of the developer DSi Shop.

The developer DSi shop uses a modified version of the DSi Browser, and most of its content is local HTML/JS. Because the app is almost entirely HTML/JS, I was able to take the HTML pages from romfs and format them to work on your browser.

Sadly, many of the pages are missing- locked behind Nintendo's development servers or just straight up gone. I patched things up wherever possible, killing any dead links and linking to otherwise unlinked pages.
Features such as the console information and DSi specific operations are also missing/broken (as is to be expected when you're running a DSi app on a PC). I tried filling in the blanks where I could, but it still has a way to go.
If you want to help polish up the code, feel free to submit a PR here.

I have only gotten this to work on a DSi by installing it to NAND, but hiyaCFW may work as well. Using nds-bootstrap, unlaunch, or any similar apps will introduce problems, such as the touch controls being broken, or even causing the developer DSi Shop not to boot.
