Greetings! I'm looking to extract the visuals and audio of BizHawk at every frame of a game for an A.I. project. I'm currently working code directly into BizHawk's source because the built-in Lua isn't flexible enough, to avoid taking screenshots, and to inject controller inputs back in. Unfortunately, I'm not familiar enough with application design to understand the flow of data. Can anyone familiar with the source material suggest the locations of the final visual and audio buffers at each frame (assuming they exist)? Thanks in advance.

creaothceann meant to say avi dumping code I think, which is what you should check.

I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

I probably should have been a little more specific. I'm performing calculations on this information on a per-frame basis and will use it to decide what actions to perform on the next frame. In other words, I'm not trying to take a video of a script I've already made, I'm trying to use the current frame to automatically generate a script. I'm writing it directly into the source to avoid taking thousands of one-frame videos, which could be extremely inefficient. My goal is to take the information straight from memory.

The answer does apply. AVI writer is where you find which buffer you need to grab. It's at native res by default. You can hash the contents of the buffer and store the hashes, then only compare them instead of the whole framebuffer.

I saw. I misread the post. I couldn't delete it before you replied =). I'll look into it, thanks.
