This was fun to try out, hopefully my future edits will have much better tracking.

This was done in Premiere Pro, the initial positioning and scaling was done using the corner pin effect, and the rest of the tracking was done by using the motion effect of the clip itself.

I overlayed the tracked clip on top of a video of me imitating the button presses I saw on my moniter onto my game boy, which was off. And the audio editing was done by decreasing the bass by -10db and increasing the treble by 10db. Then I added a lowpass to reduce the deeper lows, and finally I decreased the volume and swapped out the lowpass for a highpass for when I covered the speaker port with my finger.
