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.

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.

DSiWare that can be crashed

Name	Input type(s)	Status	Description
Dark Void Zero	High-Scores	Done	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.
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, it's unknown if this is exploitable.

DSiWare with incomplete analysis

Name	Input type(s)	Status	Description
Escapee Go	None	Started	Has high-scores without names, scores are ASCII null-terminated strings. Managed to semi-crash this, but system reset still worked so this probably isn't exploitable.
Legends of Exidia	Player name	None	Has ASCII player name in one file, and UCS-2 player name in a profile file. ( Even though checksum was figured out, the game does further data validtion, and deleted the hacked save. )

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.
Bookworm	High-scores and word list	Has ASCII null-terminated high-score list names and null-terminated word list strings. ( No crash, just nice very high scores, and very long words displayed. )
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.

DSiWare that probably don't have vulnerabilities

Name	Input type(s)	Description
24/7 Solitaire	None	No high-scores or string input.
Aquia: Art Style Series	None	No strings
Brain Age Express: Arts & Letters	None	No strings in savedata.
Brain Age Express: Math	None	No strings in savedata.
Dr. Mario Express	None	No strings
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.
