A basic demo showing a working (although sub-optimal) dynamic split-screen. When the players are close enough, they share a single screen. Once they get far apart, a variable-slope split separates players depending on their relative positions.

Unfortunately, this is not a game as there's nothing to do except roam the map...

Developed in C (and a bit of assembly) with PVSnesLib using the assets from graphics examples (https://github.com/alekmaul/pvsneslib/tree/master/snes-examples/graphics) during SNESDEV 2025 (https://itch.io/jam/snesdev-2025)
