Oh it's the same one, it was just mislabeled as MCOG1 on the old board. Sorry for the confusion.

There's two version though. The second one has better sound quality, more dungeons (more challenging too), magic, items and monsters and some minor spelling mistakes fixes, but it's far much bigger (over 60 MB due to higher mp3 bitrate) and it's only in english

yeah this is why I stopped making RPG Maker 2003 games. I may give it another try but I might use VX instead if I ever get it to work
