**Ce programme nécessite [DevKitPro pour 3DS](https://devkitpro.org/wiki/Getting_Started).**
|
||||||
|
|
||||||
|
Makefile récupéré des fichiers exemples de Devkitpro.
|
||||||
|
|
||||||
|
Programme affichant un sprite basique.
|
||||||
|
|
||||||
|
Le code est aussi documenté que possible mais certaines bibliothèques ne donnent aucune information sur les fonctions.
|
||||||
|
|
||||||
|
Si vous voulez faire votre propre sprite, il faut modifier le fichier `gfx/sprites.t3s`.
|
||||||
|
|
||||||
|
J’utilise l’émulateur [Citra](https://citra-emu.org/) pour lancer le fichier compilé.
