Is there a category I'm able to run with the steam version which is Sega Mega Drive and Genesis Classics?

Hi, are you sure you're not confusing monster world and monster land? 😛

i wont blame you, the serie is a bit confusing, there are 2 wonderboy III, Monster World is not the first of the Monster World serie, hum, here is a breif:
_Wonder boy: on master system
_Wonder boy in monsterland: first of the monster word serie, (actually wonderboy II)
_Wonder boy III : The dragon's trap (second of monster world serie) / Wonder boy III : The dragon's lair : 2 different games 😕
_Wonder boy in Monster world : serie is now on Genesis / Mega drive - actually wonder boy IV, (third in monster world serie)
_Monster World IV: actually wonderboy V, named because fourth of monster world serie

Whoops my mistake I'll post my question on the other forum.
