When downloading GP4 Tweaker 1.0.4.5 Reloaded, there's a small app called
keycode.exe to find virtual key code and scan code from the keyboard. With the help of this tiny app, we can set/change appropriate values stored in
[GP4 folder]\gp4tweak_data\keybind.ini if we wish to remapping keys that used by GP4 Tweaker. The keybind.ini file itself uses key mapping based on US keyboard layout, which is could be different for other layout.
In reality, doesn't matter who's
right but most important is who's
left.
