Hello, World! I made another fix, this time it's Piggeh's Modern Sonic Engine! This one is a work-in-progress. There's still some issues I haven't patched out yet. I'll try to get to them in the future. Press P to pause. I forget whether I modded that in since we can't access enter any more. Use the arrow keys, Z and X to control Sonic.
(I'll try to get the credits stage working but here's what's important) Thanks to @MrLog for the 360 Sonic Engine, and @piggeh for his remix of that, Modern Sonic Engine. Music is from Sonic Unleashed. Some graphics and sound effects are from or based on various Modern Sonic games. Sonic the Hedgehog belongs to Sega and Sonic Team.
