FreeIntv Keyboard Hack

Hi Folks,

I am quite new with this topic. I would like to use the FreeIntv emulator but not with a controller, instead I would like to use a keyboard. For jzIntv I know there exists a tutorial to create a keyboard hack file.

Is it possible to create something like this for FreeIntv? The idea is to use the keyboard numpad instead of the buildin mini keypad of the emulator. If possible a detailed explanation would be helpful! Thanks for any help! :blush:
