The ending credits vary depending on how many Chaos Emeralds you collected throughout the game:
- If you collected all 7 Emeralds, at the end Dr Robotnik will be seen jumping angrily on "THE END."
- If you didn't collect them all, Robotnik will be happily juggling the Emeralds you missed over the words "TRY AGAIN."
In the late 1980s/early 1990s, Sega of Europe released a modified version of the Master System and Mega Drive hardware for use in arcades. This multi-cart system was known as Mega-Tech, and the JAMMA version (Mega Drive only) as Mega Play. This machine could host up to eight cartridges at once, meaning the arcade-player could choose any one of eight games to play; both 'Sonic the Hedgehog (1991) (VG)' and 'Sonic the Hedgehog 2 (1992) (VG)' were amongst these games. Other than many notable differences, this version of Sonic 1 was identical to its European Mega Drive counterpart other than the ever-present countdown restricting your play time; you get an additional 3 minutes for each coin you insert. The Mega Play version has a few differences: it's based on the Japanese version of the game, complete with scrolling clouds (see above); the timer counts backward instead of forward, with rather strict limits for each stage (fortunately, if you die and touched a Start Marker, you'll begin at the Start Marker with a reset countdown); any extra lives collected are ineffective (if you want to continue your game, you need a pocket full of quarters); there are only four Zones to play (Green Hill, Spring Yard, Star Light, and Scrap Brain, the lattermost of which is missing its final Act); there are no Special Stages (even if you jump into the giant Ring at the end of an Act, you'll just start the next Act as usual); and finally, there's no credit roll - instead, once you complete the game you are asked to enter your initials on a high score screen.
