Initial commit of zxbox - a ZX Spectrum emulator ported by Anton Romanov. It theoretically runs on all targets, but I have not included it in the Archos builds because it is just too slow to be usable. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10950 a1c6a512-1295-4272-9138-f99709370657

Allow the Sansa e200 UI simulator to be built. Thanks to Andre Smith for the nice image of the Sansa. Lots more to be done including testing and tweaking the keymaps and modifying the plugins for the Sansa's 176x220 LCD. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11351 a1c6a512-1295-4272-9138-f99709370657
