Most Master System games are fully compatible with a Sega Genesis controller. There are a few that don't work with Genesis controllers though. The reason for this is a Japanese/export region check the games perform which toggles the select line on the controller port. It's supposed to be reset, but these games fail to do that.
This applies to both Master System games on a Master System AND Master System games on a Genesis.

- Alien Syndrome
- Bomber Raid
- Great Volleyball
- Montezuma's Revenge
- Penguin Land
- Tennis Ace
- Shanghai
- Where in the World is Carmen Sandiego?
