I'm trying the new version "Z64KNewUI.jar". I can run it at full speed without noise. But, I only have the alphabetics keys. I have got any numerics or symbols. I'm working with a french keyboard. More precision, the numeric keypad works and I have the ';' on the key 4 of the alphabetics keyboard.
The keyboard support has been very challenging, especially for keyboards with limited keys on them. I still need to do a lot of work on internationalization of the newUI. I will look into creating a virtual keyboard at some point but for now the physical PC keyboard can be configured via the keyboard editor under the tools menu. I also plan on including full language support in the future. At the moment I am only using Google translate so I will be asking for contribution from native language speakers to assist with proper translation.
