Sonic & Johnny is a homebrew platformer for the SEGA Genesis, entered into the 2022 Sonic Hacking Contest. It was created by an independent developer as a fan project, not an official Sega release. The exact origins of the game are tied to the contest, meaning it was built from scratch or heavily modified from existing assets, but its status as a contest entry gives it a place in the hobbyist scene. As a Sonic-style platformer, you control either Sonic or his new partner Johnny through side-scrolling stages. The core loop involves running at high speed, jumping over pits, collecting rings, and defeating enemies by spin-attacking. Levels are likely designed with multiple paths and collectibles to encourage replay, but specific mechanics unique to Johnny are not widely documented. The game follows the classic Genesis era formula of reaching the end of each stage while managing health through rings. Sonic & Johnny is worth trying if you are curious about the homebrew Genesis community, though it is a niche title compared to official Sonic releases. Its contest entry nature means it may be shorter or less polished than commercial games, but it offers a glimpse into fan creativity on vintage hardware. For collectors of obscure Genesis ROMs, it is an interesting curiosity from the 2022 contest cycle.

How to play Sonic & Johnny online

Getting Started

After loading the ROM, press Enter to start. The game will show a title screen; pressing Start again likely enters the main menu where you select a character. Use the D-Pad to highlight options and X to confirm. Most homebrew Genesis games use simple menus without language barriers, even if English is assumed.

Once you pick a character, you are dropped into the first level. Move right with the D-Pad and jump with X to avoid obstacles and defeat enemies. Collect rings to protect yourself from damage. The level ends when you reach a signpost or goal marker. Your score and rings carry over, but no save feature is present - you must finish in one sitting.

New players should focus on learning the level layouts and finding hidden paths. The game offers basic Sonic-style physics: rolling down slopes builds speed, and jumping on enemies bounces you upward. If you lose all rings and get hit, you lose a life. Continue from the last checkpoint, but the entire run ends when you run out of lives.
