Hi!
Sorry! You are right! The disk swapping is an issue we not fixed yet. It allways asks for disk1.. :S (mainly becouse our focus was on the HDD version)
1. You start the game with the "QuestMenu.adf"
2. For the first chapter you need to swap to "QuestLevel_Chapter_1-Disk_1.adf".
3. Next you need to swap to the "QuestLevel_Chapter_1,2.3.4-Disk_2".
If you play in emulator (or a real HW that has a HDD) we adwise you to play the HDD version! In that case you dont need to swap floppys, the loading is faster and you have music.
Simply add the content of the zip file (Quest.zip) as the directory of your DH0 and boot from that.
