This lists DSiWare that might have vulnerabilities, like strcpy or sprintf from savedata.

Since system update 1.4.2 blocks copying *all* dsiwarehax, do not contact us about your dsiware anymore at all.

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. Don't bother if all you care about is warez and don't care at all about homebrew: DSiWareHax SD card loader will never load warez directly, only homebrew.

DSiWare savedata is extracted and modified with these tools: https://github.com/neimod/dsi save_extract and save_adjust both require sd_key, but we will not redistribute this key.

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.

DSiWare with finished analysis
