http://ubuntuforums.org – when i type 'make' it prints out Code: make: *** No targets specified and no makefile found.  Stop. But there is about 3 makefile files (Makefile.in, Makefile.check and makefile.ms)... I am stuck here, i really need this emulator. I also tried 'make -f Makefile' but same problem. Thanks in advance. :D (Hardware)
