I updated Maelstrom today to include the version that person said he got working with Wine on a Mac. There are now 4 versions included: DX8 in 32 bit, DX9 in 32 bit (both of these are WinXP compatible), DX9 in 64 bit and now a "Wine version" compiled with the VCruntimes from the Visual Studio 2012 distributables. You can try it. If you purchase it and it doesn't work, let me know and I will gladly refund you. I don't really have a way to troubleshoot Wine, so I probably would not be able to resolve the problems.
