    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 ;)
