Although its not a Wineskin issue, they won't support you here at all. I know you posted this over on the Wineskin forum as well, but there is little I can do over there for game specific problems. If you reproduce the problem using normal Wine and XQuartz, then they'll help here. Being the Wineskin uses stock Wine its actually possible to run it command line right from Wineskin and its normal Wine usage, but you have to change around your path and stuff... I don't know why that wouldn't be supported though. I'm thinking of putting together a HOWTO on the FAQ on how to run the Wine build command line under XQuartz for testing and maybe that will be accepted here since its stock unmodified Wine already anyways.
