    IMPORTANT NOTE: This project has moved to Github: https://github.com/pkozelka/libxml2-pas Pascal units accessing the popular XML API from Daniel Veillard ( http://www.xmlsoft.org ). This should be usable at least from Kylix and Delphi, but hopefully also from other Pascal compilers (like freepascal).

    WinDS

    WinDS

    Windows XP reimplemented on Nintendo DS

    WinDS is a Reimplementation of the OS Windows(R) XP(R) on the Platform Nintendo DS. Since i started coding Apps for the NDS, my goal was to write a program, called WinDS, which does (nearly) the same as the real appy by Microsoft. In contrast to other little NDS-Operating Systems, just like Woopsi etc. you can code your own Application in Lua for WinDS: just copy the Code onto the FAT-Disk and execute it from within WinDS! This is what makes WinDS so unique. The New Beta 0.95 is out, it features - 52 Classes that are already available within Lua - 25 different types of user interface classes - 8 different predefined dialogs which makes it the perfect GUI sandbox for DS. PS: More time without update means: next update will have even more improvements, as i am still developing ;)
