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.

Download original app:

I have found 3 different versions of this app. I am not sure what the differences between the apps are, though I will look into that.
I used the files from DSi Shop (Debug) (shop.HNFC.Release.v1536.tad).srl for my demo.

DSi Shop (Debug) (shop.HNFC.Release.v1536.tad).srl
DSi Shop (shop.HNFC.Release.14231.tad).srl
DSi Shop (shop.HNFC.Release.thumb.tad).srl

I have only gotten DSi Shop (Debug) (shop.HNFC.Release.v1536.tad).srl to work on a DSi by installing it to NAND, but hiyaCFW may work as well (I haven't tested that yet). 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.

As for the other two DSi Shop versions, booting via NAND produces a 293003 error. They do boot on unlaunch, though suffer from broken touch controls.
