Put Games on an R4i-SDHC Guide
The R4i-SDHC is a Slot-1 flash card, with compatibility for the Nintendo DSi. It allows you to run homebrew software, greatly expanding the functionality of your Nintendo DSi, letting you play movies, listen to music and store backups of games directly on the SD memory of the flash card. This saves you time and space, allowing you to carry only one flash card with dozens of games, versus carrying the individual cartridges for each different game. Loading games onto your R4i-SDHC can be accomplished in a few short steps.
