This item addresses Bug [1463434] (ZAK FM-TOWNS: Keyboard shortcut problems). This patch adds F1-F4 switch key handling in Zak FM-Towns. This functionality was not coded in the scripts (checked with descumm) and probably is not contained in the original game either (the keys didn't work with the UNZ FM-Towns emulator). Although it might not exist in the original game, I think its a nice feature because those keys work in every other version of Zak except FM-Towns. At the end of the game while getting the white cristal it is very helpful.

I added the patch to ScummVM SVN.
