I don't think that collection has the 8 bit version of Mean Bean Machine. Speedruns of that version are submitted here: https://www.speedrun.com/drmbm

Yes you can submit runs playing the game on Sega Genesis Classics.

Hello! I have sent a request to get a separate leaderboard for the Game Gear version of the game. I'll let you all know when I receive an answer of if the game request gets accepted or rejected.

I forgot to mention one of the mods is mod for the Puyo Puyo Series and for some of the Puyo Puyo games he's the only mod, wouldn't that leave some games without a mod if I get him removed or would he just be removed from the game I request?

So 2 weeks ago, I submitted 2 runs for Dr. Robotnik's Mean Bean Machine but they're still awaiting verification. I decided to contact the game's 2 mods by messaging them on this site and saw that one of them has been offline for 2 years and the other for 3 months. Since they were offline for so long, I decided to find another way to contact them and was only able to find them on Twitch. I decided to dm them there but it seems they've been offline for a while there too (One was last live 3 months ago, the other was a year ago).

So I was wondering, while I wouldn't mind waiting a bit longer, what should I do if none of the mods respond my dm and verify my runs?
