hiyaCFW is a custom firmware for the DSi that allows the use of an "SDNAND" – running the DSi Menu from the SD card. It used to be required for most other homebrew to function correctly, but has since fallen out of favor as it's complicated to set up, slow on large SD card, and mostly unnecessary. An install of hiyaCFW is console specific.

Instructions

Installing hiyaCFW is generally done using the HiyaCFW Helper, a PC program which takes a NAND backup and does everything required to install hiyaCFW. Once it has installed hiyaCFW, all that needs to be done is to run the "hiya.dsi" file on the root of the SD card.
