ZXDS is an emulator of Sinclair ZX Spectrum for Nintendo DS, written by Patrik Rak. It is steadily reaching a mature stage of development, and it already has some noteworthy features, like accurate emulation of Spectrum 48k, 128k and Pentagon models (including sound), or support for TAP/TZX/PZX tape files, TRD/SCL disk files and RZX playback files.

Changes:

+ Support for download of files from HTTP and FTP servers over WiFi.
+ Virtual directory system for creating arbitrary listings of both local and remote files.
Config for World of Spectrum, RZX Archive and Demotopia data feeds included.
See online.txt for how to create the listings and setup your own servers.
* The data_path, saves_path and screens_path are now configurable.
* Help now finally uses the variable width font as I always intended.
* Stick to the Zilog behavior regarding SCF/CCF undocumented flags.
* Built with the latest devkitPro release, should solve most libfat/DLDI issues
