I have no idea what I'm doing wrong. Could some one tell me how to install arena and DF. I'm able to mount c: and stuff but for arena I get "can't load up /arena" And DF is about the same. Am I supposed to put the arena folder and DF folders in the dosbox folder?

When I installed Arena, I didn't put the folder into another folder, but when I installed Daggerfall I made a folder called dosgames.

As for Arena, did you actually install the game? There should be a document called Arena106 setup in the Docs folder in the Arena folder that should help you set it up.

As for Daggerfall here is a set of http://www.gamesas.com/bgsforums/index.php?showtopic=1012957 by Taemos.
