nds-bootstrap is a homebrew application used by TWiLight Menu++ to load DS cartridge dumps and DS-mode homebrew from the Nintendo DSi / 3DS SD card.
It can also be used on flashcards, however compatibility on flashcards is lower so it's primarily intended for homebrew-only flashcards and flashcards with low compatibility.
To see if a game is compatible with nds-bootstrap, check the compatibility list:

nds-bootstrap can use Action Replay cheats via a
usrcheat.dat database, which needs to be in
sd:/_nds/TWiLightMenu/extras. Once the database is there, you can select which cheats to use from a game's per-game settings menu in TWiLight Menu++.
DeadSkullzJr's cheat database is recommended as it's the largest and most up to date:
Alternatively, if you would like to make one yourself, you can use use R4CEE on a computer:
Keep in mind that nds-bootstrap's E-type cheat implementation is unstable and as a result, your code may or may not work. This is not a fault of the database, and we hope to get this issue fixed in nds-bootstrap soon.
