---++ Port Status

Due to the similarites to various PP and iriver Players, the Port is already pretty advanced.

A bootloader and main binary can be built [[UsingSVN][using code in SVN]]. The port is mostly functional (see below), but keymaps could use more work.
---++ Bootloader

Currently, the bootloader replaces the OF. Dual boot is supported by booting either /.rockbox/rockbox.mi4 or /SYSTEM/OF.[mi4|bin].In order to boot the OF, press the left button immediately after the Rockbox bootloader pops up (a half second before may work also, it needs some timing).

---++ Installation
   * Connect the Samsung to your computer.
   * Get the bootloader from http://download.rockbox.org/bootloader/samsung/yh925/ (Samsung YH925), from http://download.rockbox.org/bootloader/samsung/yh920/ (Samsung YH920) or compile it yourself from SVN (The bootloader file is named FW_YH820.mi4 for the YH820, PP5020.mi4 for the YH920, and FW_YH925.mi4 for the YH925). See HowToCompile
   * Rename the OF (original firmware) file in the SYSTEM folder to "OF.mi4" if you want to preserve dual boot. *Note:* The system folder is hidden by default. You need may need to activate "Show hidden files and folders" if you're on Windows.
   * Overwrite the OF file in the SYSTEM directory on your player.
   * Get the Rockbox build from here: http://build.rockbox.org/ (Samsung YH92* only as of now) or compile Rockbox from SVN on your own. Then extract rockbox.zip on the Samsung.
   * *Safely* remove the device, unplug and let it boot into Rockbox.
