Hi guys,

This game was released for Master System a long time ago, and in Brazil we had a company who was an official game licensed by SEGA based at this game they just changed the characters sprites for sprites for a brazilian comics characters called Monica's Gang.

When this new version was released some fans of the game did the same with this new game. I want to know if this mod is valid for run. Is just a cosmetic mod to put the Monica's Gang characters.

Sorry to say, in this case those wouldn't be valid on the leaderboard. That shouldn't stop you from doing runs of it if you want, of course! In this case they just wouldn't be able to be listed alongside stock game runs.
It's unlikely that there's anything problematic about the mod, but we're sticking with the unmodified game - the team did a great job of keeping everything comparable across all platforms, so PC/PS4/Switch can compete on even ground.

Ok, I understand Tina, thanks for awnser
