Wonder Boy in Monster Land (Sega Master System)

Wonder Boy in Monster Land is a Master System port of the similarly titled Sega/Westone arcade game Wonder Boy: Monster Land and the first version of the game released internationally. A bit harder than its coin-op original, due to the lack of a continue feature, but players able to persevere through the added challenge will experience an all new stage made exclusively for this version. This port was released in Japan under the title of Super Wonder Boy: Monster World, making it the first game in the series released under the Monster World spinoff brand.

Regional differences
The Master System version of Monster Land has a region switch that changes the game's title and language when played on a Japanese system. The same holds true for its Japanese counterpart, Monster World, when played on a western system, but instead of having the final English version of the game, it features an earlier version of the localization with a slightly different title (Super Wonder Boy: Monster Land).

It is worth mentioning that while some Master System cartridges had the game's title misprinted as Super Wonder Boy in Super Monster Land on their labels, these misprinted cartridges are otherwise identical to the final English release.

The early English version (dubbed Version 1.0) differs from the final version (Version 1.1) by having a different script and being much closer to the Japanese version in terms of difficulty. Specifically, enemy bosses have more health in both, the Japanese version and the early English version, than in the final English release.
