emuMMC

emuMMC is a replacement SDMMC driver for Nintendo's Filesystem Services that allows users to load emulated eMMC data from an SD card or vice versa. Notable features include arbitrary backend selection, on-the-fly hooking and patching with a single payload for all supported Horizon versions, and full support for the redirection of the `/Nintendo` folder to arbitrary paths without character restrictions. Additionally, emuMMC supports file-based SDMMC backends, enabling the loading of eMMC images from backups.
