Arduino Pro Micro ATmega32U4

[0zzy]

Hi all!
My gpio are in use by rgbdual, so i was looking for a different solution to build 2 arcade oontrollers.
I have build them using 2 Arduino Pro Micro (clone) with ATmega32U4, and this sketch.

It works fine when i am in game, but every time ES is loaded, the menu scroll up until i move joystick, after that it stops and i can use it normally.
It happen after the boot process and after i quit a game, so every time ES is reloaded.

Is there any expert on arduino or have any idea about it?

Thanks

I'm wrong, does not happen quitting game or reloading ES after updating game list for example, but only after the boot process.

It happend even if i have unplugged the microswitch UP

// Pin 9, A9 = Button 1
// Pin 8, A8 = Button 2
// Pin 7, D7 = Button 3
// Pin 3, D3 = Button 4
// Pin 2, D2 = Button 5
// Pin 4, A6 = Button 6

// Pin 20, A2 = Select Button 1
// Pin 19, A1 = Start Button 2

// Pin 5, D5 = Other Button
// Pin 6, A7 = Other Button
// Pin 18, A0 = Other Button
// Pin 21, A3 = Other Button
