This is a second post I've decided to make, specifically about things I discover while playing Corum III in English. Part One, about installing and getting the game working, can be found here.
I've considered making a walkthrough of the game, but I don't think there's any way for me to do that without including spoilers, so for now I will simply list any significant errors I find, or useful materials.
I found it a little frustrating and confusing trying to find where people live in town, so I made a map with everyone's name on it. I assume all the names are the same between the BeOS and Windows versions, but I only checked a few names. You should be able to save the full-size map by right clicking the image and clicking "Save link as"
In the Windows version, the second Ranford Mission from the Adventurer's Guild, there is a mistake. It says you need to deliver the letter to Irene, but that is a lie. You need to deliver the letter to Moanne. This mistake does not exist in the BeOS version.
I had some trouble with button presses not always registering. It might be easier with keyboard rather than gamepad.
