I think I've found a workaround. Download new joyll
here. You need to configure Poseidon to map the buttons to two lowlevel ports.
First set Port 3 of the lowlevel.library emulation to "Merge with USB" just as Port 1 already should be.
Then add portmapping for the additional buttons like:
Button 11 -> Digital Joystick | Any | Assign <some button> (port 3)
...
After that's been taken care of, you should be able to configure joyll as normal, but now it should pick up the "B-port" events as well, and thus allow more buttons to be used.
Only tested briefly on AROS, so the MOS plugin is completely untested (don't have any hardware to test it on anyway, so...)
