You could add a category for mega drive. I don't know if they had proposed it before but if not, I would like them to make it to the category to upload my run in that version

I also offer myself as a moderator in case you need it, since I love this game in all its versions

Could there be differences between the versions to warrant a split? You could upload the run to the current board without any issues.... I think the rom is exactly the same but I could be mistaken.

I have not yet played the version of megadrive but from what I have seen it is the same, they should add Megadrive in the list of platforms anyway and in the category it would be something like "genesis / megadrive"

When I have some time I will play it to see if there is any difference
