The author m4xw has developed emuMMC, which is a replacement for Nintendo's Filesystem Services' SDMMC driver. It is designed to be compatible with Horizon versions 1.0.0 to 16.0.0.
**Only one payload required for all versions.
*File-based SDMMC backend support (from SD).
**This allows loading eMMC images from hekate-backups (split or not).
*SDMMC device based sector offset (currently eMMC only).
**Raw partition support for eMMC from SD with less performance overhead.
*Full support for /Nintendo folder redirection to a arbitrary path.
**No 8 char length restriction.
*exosphere based context configuration.
**This includes full support for multiple emuMMC images.

Run <code>./build.sh</code> and copy the produced kipm (Kernel Initial Process Modification) file to <code>/bootloader/sys/</code>


=== Atmosphere ===
