I noticed that too. For me left and right works but not up and down. It also is the case in the ao486 core - both systems originally used analog readouts.
It happes with these gamepads/joysticks I tried:
- Logitech Rumblepad 2 - wired
- Logitech F710 Wireless
- Xbox 360 Afterglow wired controller by

The other cores work well - but I reckon the games and software I tried only used the digital atari style readout (C64, A2600, Genesis).
