So, I found the Sonic game for the SEGA Pico! It’s pretty cute as it features Green Hill Zone, Casinos, Scrap Brain Zone, and other wacky locations.

You gotta love that picture of Eggman just nonchalantly stealing the Chaos Emerald.

The Japanese version of Sonic the Hedgehog Gameworld - it has a colour manual and superior packaging. The plastic case reminds me of vintage software for Commodore and Atari computers.
