The applications now work again, after updating the following packages to version 20120127: app-emulation/emul-linux-x86-baselibs-20110928 app-emulation/emul-linux-x86-xlibs-20110928 app-emulation/emul-linux-x86-medialibs-20110928 app-emulation/emul-linux-x86-soundlibs-20110928 app-emulation/emul-linux-x86-sdl-20110928I think I had tinkered with them before, though, as one of the application's title in the task-bar would state "SDL_app" for the brief moment it ran, but I can't remember exactly which versions were still available from Portage. Tested with wine-1.3.37 and 1.4. With 1.4, I also downgraded the emul-linux packages back to the previous version, and the applications would indeed fail to work again. Thanks again for the suggestions. Blubb~
