Some bugs in MIST core

Hi!

Very nice reimplementation!

But found some bugs:

1. Certain games simply don't run (i.e. Ladder).
2. In the menu the highlighted area disappears below the 'Autostart' funcion, but works (there's an invisible 'Reset' item). Someone mentioned earlier (perhaps Sorgelig) that only 7 rows fit to one page of the menu.
3. Couldn't use any of the games with joystick (tried all the joy and kb. settings combinations, tested USB gamepads and retro DB9 devices as well).
4. Some games use strange keysets to control the game, but knowing that the original machine had ABCDEF keyboard layout instead of the standard QWERTY, that's not a surprise.

Keep up the important work, I really like these Eastern European computers!
