Last week, a working Genesis cartridge that tied into the upcoming Sonic 3 movie was delivered to press and influencers. Among the features were character select screens, movie posters, and a sequence involving Shadow chasing Sonic on his motorcycle, and a cheat code that unlocked the November 25 release date for the next trailer.

Now, its creator Brielle Garcia has revealed to GamesRadar+ what had to be cut from the Genesis cart's measly 4 MB of storage.

Despite the technical workarounds, Garcia – who produced an entire music video featuring characters getting trapped in a Genesis as an early test – found working alongside Paramount to be creatively freeing.

On the reaction to the cartridge from the ever-passionate fanbase, Garcia added, "The sheer joy from people as they realize it's a real working cartridge with new content has been my highlight… I really wanted it to be something that Sonic fans would appreciate, as I'm a huge Sonic fan myself."

I'm the Senior Entertainment Writer here at GamesRadar+, focusing on news, features, and interviews with some of the biggest names in film and TV. On-site, you'll find me marveling at Marvel and providing analysis and room temperature takes on the newest films, Star Wars and, of course, anime. Outside of GR, I love getting lost in a good 100-hour JRPG, Warzone, and kicking back on the (virtual) field with Football Manager. My work has also been featured in OPM, FourFourTwo, and Game Revolution.
