Loop is:
- go in options
- edit teams
- press 'C' -> create team
- put whatever as name, press 'C' on player menu -> finished
- press 'C' on team selection -> finished

- exit emulation, reload with steps 1, 2. Check the created team is there at the end of list (concealed in Teradrive because this clearly needs a PAL machine).
Somehow megadriv still seems unhappy in its handler, probably the legacy implementation fumbles over?

This needs a second look about the transliteration (best as I could by joining together with the similar title, cfr. link).
