This is the first game that has exclusively been designed for the REU, to make a fast and smooth full-screen scrolling version of Sonic with little compromises.
This game is a direct port of the SEGA Master System 8-Bit version of Sonic the Hedgehog, with about 64 KB of code hand-translated from the Z80 to the 6502 architecture.
The game will be released as a free download on December 19th, 2021.
It requires a C64 or C128 (in C64 mode), a compatible REU of at least 256 KB, a compatible drive (.d64 and .d81 images will be provided) and any joystick or gamepad (no extra buttons required). On NTSC, a C128 or other CPU accelerator is highly recommended.
In the mean time, here's a trailer and some screenshots:
