MAME WiiMote issue

[Banacek]

Just want to start off by saying thanks again for all the hard work. I'm using GroovyMame and GroovyArcade and loving it.

So I decided to try using WiiMotes as light guns again. Both Wiimotes are recognized by the system, and in LXDE the WiiMote works like a mouse perfectly. The issue is when I start MAME. The Wiimotes are recognized by MAME, but it's like the aren't calibrated or super sensitive. The cursor just moves to the sides of the screen constantly. It's almost impossible to keep the cursor in the center. and it's not really lined up at all.

Anyone have any ideas on how to fix?

Thanks!
