When I first saw Titan’s Overdrive 2 demo I was blown away, both by the presentation itself and by how in the world they managed to push that out of the Mega Drive. After how much I struggled to get Overdrive 1 to work in my emulator, I just assumed that getting Overdrive 2 to work was out of reach.
The Titan Overdrive and Overdrive 2 Mega Drive demos are well-known for pushing the Mega Drive / Genesis hardware to its limits. I decided to try the first one in my own Genesis emulator and see what it would take to get it working!
