detect certain input combination...

[HarveyBlunts]

I am a very competent c programmer and I'm comfortable with assembly as well. That being said, this is a fairly complex program to dive into

I have a gamepad hooked up that I use with zsnes. What I'd like to do is modify the source such that if the user presses L+R, or Start+Select, or some such combination, then zsnes exits.

I'm not even sure though where the main executive loop occurs at, or where the input is processed. Can someone point me to where I should be modifying, and perhaps give me some pointers on doing the stuff I'm attempting to implement?

really, thank you guys so much for this incredible program and the prompt&awesome support i've gotten from these forums thus far.

well I dug through the code until I found Main_Proc, and I added this code to the SDL_JOYBUTTONUP case (after some debugging to determine the specific codes for my buttons):

if (pressed[266] && pressed[267] && pressed[262] && pressed[263]) exit(0);

This works, if I press L+R+Select+Start it exits.
Is this call to exit(0) sufficient to properly close out zsnes, or will I leave a bunch of stuff initialized doing that? I did see a number of atexit calls, so i suspect im safe...

We do stuff via atexit(), so with v1.5x, calling exit() is fine.

Obviously editing sdllink.c makes your change port-unique. If that's not a problem for you, then that's fine.

However, you might want to choose your exit input wisely, as many games use L+R+Select+Start as a soft reset trigger.
