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.
== Total listed DSiWare ==
Before you contact anyone about your dsiware, please make sure your dsiware is _not_ listed on this page anywhere.


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


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.

| Player name
| Done
| None
| 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.
| Has an UCS-2 player name. It's unlikely this can be exploited, seems to crash /w out-of-bounds array-index.

|-
|  Fieldrunners
|  High-Scores
|  The xml, ".plist", in the game is used for storing savadata which contains high-score strings. Using a very large string crashes the game leading it to stack buffer overflow. The game has already been exploited through [https://github.com/yellows8/dsi/tree/master/exploits/fieldrunhax fieldrunnerhax].
|-
|  Frogger Returns
|  High-Scores
|  Has ASCII high-scores. strcpys to a static buffer from savedata, unknown if this is exploitable but there's only <10KB free space available(way too low for a payload) so meh.
|-
|  Guitar Rock Tour
|  High-Scores
|  Has ASCII high-score strings stored in the savedata. Using a very long excessive string can crash the game to lead into a stack smash. This game was successfully exploited through [https://github.com/yellows8/dsi/tree/master/exploits/grtpwn grtpwn].
|-
|  Legends of Exidia
|  Player name
|  Has ASCII player name stored in the savadata. Using an extensive long string will cause a stack smash to saved registers and can eventually be exploited through [https://github.com/yellows8/dsi/tree/master/exploits/exidiahax exidiahax].

|-
|  The Legend of Zelda: Four Swords Anniversary
|  Savedata filesize
|  The game has 2 savefiles. When one savefile fails to load (larger than a usual savefile), the game loads the backup save and will continue load without any errors. That being said, one can crash the game with a larger game filesize to attack the heap and successfully overwrite the stack registers including the pointer counter. The game has already been exploited through [https://github.com/yellows8/dsi/tree/master/exploits/4swordshax 4swordshax].
|-
|  UNO
|  Profile names
|  Has ASCII Player name each for of the 5 save slots. The game was crashed with a very large player name which overwritten the stack registers including the pointer counter. The game was successfully exploited which is known as [https://github.com/ChampionLeake/UNO-pwn UNO*pwn].
