Nobody said that X1000 needs to emulate all classic software. All software which doesn't use hardware directly works (pagestream, imagefx, photogenics, ...). Most of games (+protacker and some older software) don't use operating system and they require emulation using euae. MorphOS has the same (similar) abilities to run amiga software. There is Aros also but it doesn't run amigaos programs on any decent hardware.
