Hi again, in the last hour I´ve run LLchess within a debugger and I found the problem: it´s your method of checking the keyboard and testing the scan codes which doesn´t work for European keyboards! E.g. you use ´cmp ax,1579h´ (after an INT 16h) to test for ´y´, but this scancode doesn´t exist on a German keyboard. So I´ve changed a few bytes (e.g. the command above to ´nop´ and ´cmp al,79h´), and now ´y/Y´ also works for a German kbd! :) But there are still some other key combinations not working here (Shift+´, Alt+\, ...), but I´m sure that I´ll also be able to solve those problems with patching some more bytes. (The better method would of course be, not to use such strange key combinations that are not available on all national keyboards) Btw, during my testing I´ve also found some undocumented keys: e.g. Alt-1, Alt-2, Alt-K, Alt-L, ... ??? I see, your program will take me some further hours in the next days ... ;-) Best wishes to you, Franz.
