I forgot that I made a recording of the method I used for a random task here a year or two ago. We couldn't find the horse graphics, so I made a super hackey method: I compiled DOSBox with debugging support and then dumped two frames from VGA video memory. The frames were identical except for having the horse on screen. I also had to dump the VGA palette, which required assembling and injecting a small program to dump the palette to memory.
Someone ended up finding where the horse graphics lived, but there's a chance this method might come in handy for something at some point. Plus it's just neat to see. I didn't see this in my YouTube account so I don't think I uploaded it here before: https://www.youtube.com/watch?v=R0La4caR2yw
