The XArcade just emulates a keyboard though, so I'm not sure how it could be any higher-level software's problem.
The very firs time i connected the joystick,Os X did it's equivalent to windows'"found new hardwatre".
"New keyboard" - I clicked thru the prompts but Os X was unable to recognise the keyboard,although it accepts it (obviously,as it functions as mentioned before) as well as the fact i am able to scroll thru letters in a text editor.
* When trying to load the game with joystick connected,
in the border of the load diagnostic page the status of the game reads as "running"??
I am running what i know to be the latest versions of all the software in question,including the SDLMame Integrator...yada,yada.
Thanks to everyone for their help.
