After upgrade to 6.0 on cedega my everquest broke . I have looked at cedega's forums and apparently its happed to a lot of people. I am currently using fiesty with cedega 6.0 install and have finally found a work around to the issue and thought i would pass it on for others who may have the same issue.

Basically all i did was to use wine to run the EverQuest.exe from the .cedega directory, the patcher runs and updates the files. But then it crashes BUT thats ok, because its seems the patcher is what was crashing under 6.0.
So after wine lets the patcher update and crashes, i opened cedega and ran eq and the patcher runs again, and sees that everything is up to date and the game runs normally after that.

Hope this helps any of those EQ junkies out there like me!
