Questions and answers about keyboard

Why my keyboard doesn't seem to respond or gets wrong output when I press some keys ?
First thing first, the routine procedure is to check your keyboard configuration on your Windows OS. Be sure that you have a correct keyboard (driver) configuration that matches your locale. This means that you should not use a certain language keyboard that doesn't match your OS language. (i.e. English layout keyboard on Japanese OS). Such use can cause unpredictable result when using blueMSX.

Beware that MSX bios chooses which keyboard layout are being used. So if you boot an European MSX machine, then you will have European keyboard layout which matches the MSX keys accordingly. You will most likely to get different output if a Japanese MSX bios is used on an English keyboard. This is how blueMSX is designed and that's a normal behavior.

It can happen that some keyboards have problems with specific keys (like the Kana key on a Japanese keyboard). You can solve this kind of problems by using the Input Editor.

Why my keyboard seems to hang when I press many keys at the same time ?
This is not a blueMSX bug, but a problem with some PC keyboards, that act very strange when many keys are pressed at the same time.

The maximum keys that can be pressed together can vary from keyboard to keyboard, and this problem can also only happen with some combinations of keys like Right + Left + End or Down + Left + Spacebar.

You can find a solution in most cases by using the keys of the numpad :

- use the Input Editor to change the mapping of the 4 arrows;
- think as 8,4,6,2 keys as arrows and you should be able to use some combinations that don't work with the arrows.

By using this trick, the above examples become 6+4+End and 2+4+Spacebar.
