wow, hmmmm. I'm not getting what your saying because the Joysticks that I can remember had an "A" and "B" button like all the quick fires series or the ubber-cool Bug!
The games I remember are like Lion Heart (I do recall you could choose from one button or two button, which I always thought was very odd), T-Zero, Zee Wolf, etc. Maybe I just lucked out and only got good games, I donno...
Now there were games that only needed one button like Road Warrior (I think that's what it is called) where all need to do is stear and shoot. Once I'm oved into my house and get my A4000T setup I'll start going through my games...
But all that aside, how lazy is not programing for the second button??!? It's like disabling the turbo in a brand new street car...
