Notes:

1. There are some SMS games require a chip that is only present on the original SEGA Powerbase adapter. This is very rare but worth highlighting. One workaround can be to insert a working game, power off and quickly swap to the non working game, deepening on your console it may retain the missing start-up code needed to play it.
2. Some games will only work with SMS controllers, again a rare bug but we mention it to help you spend more time playing. Known games that might have issues are:
   • Alien Syndrome
   • Bomber Raid
   • Great Volleyball
   • Montezuma's Revenge
   • Shanghai
   • Where in the World is Carmen Sandiego?
   • Wonder Boy in Monster Land
