No inputs recognized

[Diego9000]

I have an issue with this port since forever but just today I decided to really look it up.

The issue is: Absolute no input works.
All buttons and the touchscreen does absolutely nothing to control anything.
I double checked the settings.ini and they show as:

[Keyboard 1]
; Keyboard Mappings for P1 (Based on: https://wiki.libsdl.org/SDL_Scancode)
Up=0
Down=0
Left=0
Right=0
A=0
B=0
C=0
Start=0

[Controller 1]
Up=0
Down=0
Left=0
Right=0
A=0
B=0
C=0
Start=0

I know that this implies that no actual input was set. But I tried to replicate the ones from Sonic1/2 and Mania ports but none worked.

Since I can't figure it out the values, can anyone help me with this?
Maybe even share your settings.ini ?
