Using a gamepad to trigger hotkeys

[jsf]

Hello,
Hope eveyone's doing fine

I would like to know if it's possible to to trigger hotkeys from a gamepad with Hotkeynet or any other.
Essentially, I'm running multiple instances of of an Atari ST emulator, Steem SSE, the plan is to have a gamepad sitting next to my keyboard that would be used to switch between active windows and most importantly, to occasionally send a couple of commands simultaneously, at the same precise time, to all instances of the active and not active windows.
I have tried Autohotkey, which works flawlessly for say "notepad.exe" but it will not work for the application I want to use it with. It seems to me that Autohotkeys "controlsend" command messes up with something and the application will not detect any incoming hotkey.

Thanks in advance for any help.
