Retro Erik tested GamepadLPT with his 6 button Sega Mega Drive controller :
for using 6 buttons, he used the 5V USB supply of GamepadLPT to have enough juice.
It worked well, see it in action in this video : https://youtu.be/qsbwjXEhZYw
Latency seems very good.

He tested several games with GamepadLPT, and most worked ok :
