Describe the issue.

I bought the cart reader recently. Amazing project. I made some Mega Drive games, and I want to know if it's possible to write Master System ROM games too. I can't find it.
Thanks in advance!

This feature has not been added yet. If you're lucky and your SMS cartridge has a flashrom that supports CFI then you could try to add it yourself by following this pull request that made CFI programming on Megadrive possible: b373075
If it doesn't support CFI then you can have a look at flash.ino in hopes to find the flashrom there and then adapt the code to SMS, but this would probably be a bit much for starters.

As an alternative this seems to be a very good cartridge programmer for SMS that you can buy right now: https://www.raphnet.net/electronique/sms_cartridge_programmer/index_en.php
