I'm not sure whether this is something unique to me or not, but whether I use the 'options' or directly in the config.ini to remove +shoot1 from JOY0BUTTON1 the game always puts it back the next time I start it. I have to manually change it at the beginning of every game. (XP)

That's a new one on me, but I suspect that not many people have tried to move +shoot1 from Joy1. I'll have to try it out when I get home.

The obvious: Are you sure that you are completely clearing Joy1 from the shoot1 menu and hitting "Apply" when using Options?

Since you are new this is unlikely, but verify that you have only one installation of Vendetta and that you are modifying the correct config.ini

Actually, this is just the way the default bindings work; our config file doesn't save the fact that JOY0BUTTON1 is bound to nothing, it just removes the bind, which allows the default bind to then override it.

The obvious workaround is to just bind it to something else that's relatively harmless, like an empty alias. In fact, yeah, either add this to wgaf.cfg or type it at the console:
/alias nothing ""
/bind JOY0BUTTON1 nothing

I had in fact noticed that, but hadn't yet took it to the conclusion. Unfortunately, because I'm using the j/s software to emultate multiple, timed key-presses (under the 1s 'wait' threshold), I'll have to keep unconfiguring it manually.

Thanks for the reply.

I don't understand why the "nothing" bind wouldn't keep you from having to unconfigure it manually.

Too cool. It works. Thanks for the suggestion.
