About

nds-bootstrap is a homebrew application used by TWiLight Menu++ to load DS(i) cartridge dumps, DSiWare, and DS-mode homebrew from the Nintendo DSi / 3DS SD card.
It can also be used on flashcards, reimplementing retail-game launching functionality on cards with mediocre compatibility (including no compatibility/homebrew-only flashcards). However, DS game compatibility on flashcards is slightly lower, and can vary between different flashcards

Cheats

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:
r.pk11.us/DSJCheats

Alternatively, if you would like to make one yourself, you can use use R4CCE on a computer:
r.pk11.us/r4cce

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.
