But though , the reality is that geeky gamers have long enjoyed music playback on the Nintendo DS. One method of doing so is to use , a homebrew media player that supports MP3, Ogg Vorbis, and AAC files (the DSi supports only AAC).
To use MoonShell, you'll need the hard-to-find Revolution for DS (aka R4)-an unofficial cartridge used for hacking the Nintendo DS handheld game machine. The R4 is a Slot-1 cartridge that reads data from removable microSD cards.
-- Pop your microSD card into the provided USB card reader, insert it in your PC's USB port, and update the software (currently v1.18).
-- Download and install Moonshell.
-- With SD card still mounted, copy music files into the root directory of the card.
-- Eject the USB drive, put the SD card back into the R4. Power on, open up Moonshell, and pick a song!

As for upgrading from my DS Lite, I reserve final judgment for when the DSi is officially released in the US. But currently, the new changes aren't terribly compelling. For starters, DSi will have a shorter battery life compared to DS Lite and will sell for a higher price- US$179 as opposed to $129. Finally, the DSi will no longer be compatible with Slot-2 games or devices, such as GBA games or Guitar Hero: On Tour.
