For those that have lived in Brazil or are familiar with the infamous Wonder Boy reskin woes, Wonder Boy III: The Dragons Trap was changed in Brazil to reference the cartoon/comic franchise Turma da Mônica, replacing all of the different animal forms with different characters from the series. This conversion was called Turma da Mônica em o Resgate, exclusive for Brazil, and an example of a Master System game being changed for the market.
With the recent remake of Wonder Boy: The Dragon’s Trap on modern systems, dedicate fans decided to change the game to again reference Turma da Mônica. This includes replacing the artwork with new high quality artwork, and faithfully recreating the animations from scratch. Together, this creates a surprisingly high quality mod that is readily available for the PC version for you to play. The video description not only containing the mod, but also a presskit that contains screenshots and artwork for the mod.
In fact this mod is so good, even the official Lizardcube Twitter account threw their praise at the mod, describing it as incredible. So if you have the PC version available, maybe try it out for yourselves.
