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.

List of DSiWare with incomplete analysis

Name Input type(s) Status Description
Bookworm High-scores and word list None Has ASCII null-terminated high-score list names and null-terminated word list strings.
Escapee Go None None Has high-scores without names, scores are ASCII null-terminated strings.
Frogger Returns High-scores Started Has ASCII null-terminated high-scores. Manged to crash this game. The high-score draw function uses strcpy to copy the records' name to a static buffer. But all the functions that copy to these lists seem to use strncpy, and it's unknown what code copies from savedata records to these lists.
Legends of Exidia Player name None Has ASCII player name in one file, and UCS-2 player name in a profile file.

List of DSiWare with finished analysis

Name Input type(s) Description
Arcade Hoops Basketball High-Scores, names via settings Has ASCII high-scores with null terminated strings, no string bugs.
Dark Void Zero High-Scores No limit on length of drawn record names, no vuln with high-scores. The level var from savedata doesn't have any bounds check, this is used with array indexes. This is not exploitable since the array structs only contain char* strings and other fields, and that var is used with level class init. Level class init fail is most likely the cause of the crash which isn't exploitable, level paths are determined by if statements and the level object is used uninitialized when the level var is out-of-bounds.
Dracula No manual input Savedata contains ASCII high-scores from DSi username, and ASCII perks/powerups. High-scores doesn't have string bugs.
Paul's Shooting Adventure High-Scores Records are entered when you complete the game, names are ASCII strings null-terminated. Not exploitable.

List of DSiWare that probably don't have vulnerabilities

Name Input type(s) Description
24/7 Solitaire None No high-scores or string input.
Brain Age Express: Arts & Letters None No strings in savedata.
Brain Age Express: Math None No strings in savedata.
FIZZ High-scores Savedata contains ASCII high-scores, but all the high-scores are contained in the same string without a null terminator. A vuln is unlikely.
Gene Labs None Small savedata with no strings.
Photo Clock None Small savedata, no strings at all.
Photo Dojo Handwritten character name via stylus Savedata only contains .jpg files and some tiny "save"/"info" files.
WarioWare: Snapped None No high-scores or string input.
