ZXDS v0.9.1 Beta 1 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 v0.9.1 Beta 1 Changelog:
+ Memory viewer and disassembler.
+ Tape sound is now audible in normal speed load mode (conveniently forced with R+A).
* The system log can be saved to a file now, helpful when troubleshooting.
* Cleaned up the virtual directory code, greatly reducing the amount of required IO accesses.
* Changed the confusing bouncing logic of previous displays' history to simple LRU.
* Fixed the annoying sound clicks when sound is temporarily paused (e.g., scrolling in requesters).
* Minor bugfixes in download code (HTTP continuation lines, last line EOL in listings).
! Dedicated to the memory of Jonathan Smith. Rest in Peace, Joffa.
