He Arzoo,
I was afraid that would be the case (non-existent) , normally you get a quick response but alas.
This morning I was looking at the sourcecode and found a couple.
Unfortunately there's not always a comment on what the output actually does.
So you have to figure it out yourself.
But I have 2 of them in the mameoutputs.ini and will look for more:
Ajax
Lunar Lander
Ajax has a very interesting feature among the outputs:
the superweapon button only lights up when available (now this is the kind of output I really like)
And with lunarlander the buttons light up for the selected game, so when you have 4 buttons in a row and you press the select button the lit button will move one up. Maybe in combination with the bezel it would be a great feature (the bezel also lights up the selected game and with some buttons right under your screen it would look pretty cool)
I try to describe the output in the mameoutputs.ini as good as I can, maybe when I have enough I can post them so that others can enjoy it.
Although they may need to adjust the settings somewhat.
If you are able to pull out a list of all outputs please let me know. The way I did it now is that I looked at the list that was in mameinterop doc and then looked at the source for these games but that's a little time-consuming.
