Comparing Lag and Ghosting for Every GBA handheld

I decided to grab all official GBA handhelds to make some comparisons, and I made some findings that I'll likely explore further in the future. I noticed I completely forgot to mention my methodology in the video. I used my iPhone at 240fps and recorded myself pressing a button as quickly as I could, then counted the frames between pushing the button and the action appearing on screen. For GB, I used the gun firing in Metroid 2, and for GBA I used the gun firing in Metroid Fusion. I used about 32 samples for each test and calculated the average milliseconds and in-game frames based on those numbers. Music: Route 99 (Act 1) - Sonic Advance 3
