ZXDS v1.0.0 is released. 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, not to mention the ability to download these files online over WiFi.

ZXDS v1.0.0 Changelog:
+ Custom keyboard support. See custom/readme.txt for more info.
+ Favorite/recent files lists showing up to 500 most/last used files.
+ TR-DOS disk browser for viewing both disk directory and sector data.
It can be used to insert empty disk images as well.
+ TR-DOS disk images can be now saved in SCL format, too.
* Keep the file viewer visible while enabling button input by pressing R.
* Little UI graphics improvements (nicer icons, empty requesters).
+ Added skins/light/style.cfg for those who prefer black text on white.
* Few subtle TR-DOS changes (density check, zero files SCL).
* Few subtle tape related changes (tape block flush, PZX fast loading test).
* Other subtle changes (widget help tracking, virtual files stats).
* Minor bugfixes (IN[ID](R) postdecrement, libfat lseek).
