If we could hypothetically resurrect sonic2-w.68k and run it through a disassembler, what would we find? First, we would see speed. The 68000 processor at 7.6 MHz was the heart of the console, and Naka’s legendary “Sonic Physics Engine” was a masterclass in efficient trigonometry. The code in sonic2-w.68k would likely contain remnants of a tile-based parallax scrolling system even more ambitious than the final game’s “Hidden Palace” or “Chemical Plant” zones. The Wood Zone, as glimpsed in the 2020 prototype leaks, was a forest of giant, twisting tree trunks. To render that on a 320x224 resolution, with four simultaneous layers of scrolling, required cycle-counting juju that bordered on black magic. sonic2-w.68k
