Pay closer attention to keyboard mappings. In the menu code, distinguish

between keys pressed and characters typed, so that, for example, when
the menu prompts "press 'y' to continue", it responds to the _character_
y being typed, not the key that is 'y' on an american keyboard being
pressed. Do the same when reading cheats.
