MoonShell, by Infantile Paralysiser, and all its iterations is a multimedia player for Nintendo DS / DS Lite consoles. It currently supports DPG video files, MP3/NSF audio files, and viewing non-progressive JPG/Jpeg/BMP/PNG files. In addition to this it also has support for text files with the .txt extension.

MoonShell makes full use of the dual screens with full support for the touchscreen. MoonShell also has a plug-in system that allows to compatible plug-ins just by copying the plug-in files to the appropriate folder. The program already comes with a few plug-ins preinstalled.

To those who are familiar with MoonShell however, a few things you should know. The version changes have been listed simply as "Changed default to '24kHz 2x oversampling." While this may seem big for people who actually need it, if you're happy with your older (i.e. version 1.6 was where a lot of changes took place) version of MoonShine then no need to upgrade to this newer version. You should note that version 1.6 was a beta build, while this version (Moonshell v1.71) is not a beta.

If you do decide to upgrade however, there is a note on Infantile Paralysis' site saying that you should never use your old MoonShell file with this update.

If you will be using a Super Card CF / SD / Micro SD / etc., Chism's firmware hack will have to be installed. Note that any SD based memory card will have to be formatted using Windows to use FAT (File Allocation Table) 64 KB. The details on how to do that along with the full steps for installation is in the readme file.
