So, after getting the patches applied for the Utima games on my Mac, I am just wondering how to get the .app to run the patched versions by default. For example, for Ultima 3, if I run my Ultima 3.app it runs the unpatched game, but if I run the .boxer file and make sure to tell it to run Ultima 3.com by default, it runs the patched game. How do I get it run this patched version through the GOG window when I click the .app by default? Is there a file I can edit like a config file or something? Thanks for any help!

Thanks for your help. This pointed me in the right direction. I managed to get it to work for Ultima 3. To do so, I had to do the following:

I noticed the code in Game Info.plist had the following:

<key>BXLauncherPath</key>
<string>C Ultima3.harddisk/bxlaunch.bat</string>
<key>BXLauncherTitle</key>
<string>Ultima 3</string>
</dict>

So, I opened up bxlaunch.bat in TextEdit and noticed it listed the following:

@echo off
c:
ultima.com

I changed the last line of this to say

ultima3.com

After that, when I launch the .app shortcut, it now launched the patched game.

I think it is weird that I had to do this, but I'll bet this method will work with Ultima V as well. Ultima IV worked without having to do this...
