DSiWare VulnList

This lists DSiWare that might have vulnerabilities, like strcpy or sprintf from savedata. If you know of DSiWare that has English-only string(high-scores, player name, high-scores that use username from system settings, etc) input, mention it on IRC EFNet #dsidev. Or contact yellowstar 6 at gmail dot com. Before you contact anyone about your dsiware, please make sure your dsiware is _not_ listed on this page anywhere.

It would be nice to target DSiWare that are listed under the DSi Shop most popular search: Nintendo would have a lot of difficultly removing DSiWare from that list without ticking off a lot of non-homebrewer customers. Targets not on that list will suffer the same fate as Sudoku,(removed quickly and patched less than a week) if exploits for those were released.

DSiWare savedata is extracted and modified with these tools: https://github.com/neimod/dsi

For these lists status "None" means code reversing engineering for the DSiWare wasn't started. Status "Started" means code reversing engineering for that DSiWare was started. Status "Done" means code reverse engineering was finished.
