Changes

MESS generally supports two keyboard mode command line options: '''emulated''' (the default; based on key position) and '''natural''' (command line option "-natural"; based on the character generatedby a key, e.g. pressing "z" will always generate a "z" on the emulated system, even if the keyboard positions are different). In emulated mode, keys can also be remapped in the menu: press ''Tab'', then select ''Input (this system)''.
