The game only calls the key entry routine when it needs a new key. In fact, it only call it when need to enter any key (most times, when needing to type only a number, it uses directly the keyboard columns lines...). Well, so, following the advice of Adriano Cunha, I used the same process he uses on Uzix. I call a non-documented BIOS routine that read the key matrix again and put it on the keybuffer (which I had cleaned before calling this routine, to avoid trash) as a ASCII number. I verify then if it is a "normal ASCII" (number or letter) and if yes, return the ASCII. If not, I let the game proceed with its own procedure (there is not differente between the keyboard typer for the extended keys). This is needed because the game associates special values for some control keys (PE: Home becomes 0xF0. I don't know why, but I thought it was better do not change it). This is how the mistery was solved. In fact, the big trouble was in finding a BIOS procedure that was able to ready the keyboard with the IRQ disabled... and more: a procedure that should be in the same place on every computer. These procedures are 0d12h, which reads the keyboard and fill a keymatrix structure and 0d4eh, which translates this structure into a ASCII number on the keybuffer. I don't know the specifics about these, unless the fact their addresses are unchanged from machine to machine and they work. For more info, consult the MSX BIOS.
