+#### BIOSes
+
+/!\ **dsi_nand.bin** is too big to be uploaded on this repo. You will have to add it manually.
+
+The dumps are European (EUR) for those who want the US version, it can be downloaded at this address : https://emulation.gametechwiki.com/index.php/Emulator_files#Nintendo_DS_.2F_DSi
+
+#### SD Card
+
+DSi mode is optional
+
+You can get the SD card image (**dsi_sd_card.bin**) by yourself or from the melonDS site.

+
+If you are dealing with DSiware, it is better to do it with melonDS alone instead of RetroArch.
