I tested with my gamepad and can confirm bugs with freezing and with Hard Drive Selection. I will try to fix it.
Remap click button for gamepad probably possible i must check.
SDL settings for gamepad same uae4all2 (probably differences in core of uae4arm code)
# Redefine gamepad keys to SDL keysyms, button order is:
# A B X Y L1 R1 L2 R2 LThumb RThumb
RedefinedKeysGamepad="HOME END PAGEDOWN PAGEUP RCTRL RSHIFT F14 F15 PAGEDOWN HOME LCTRL"
click work via PAGEDOWN keycode
Swap between Joystic and mouse look like supported in uae4arm too. I will try to implement switch for it.
