I have just installed the videogame emulator called xmess using the package manager. Since this had no frontend I also installed xkmame (which is for KDE but fortunately seems to work with Gnome too - guess that's normal?). Now I need to enter the different paths to the xmess executable, game roms etc. Only problem is: what does the xmess executable look like (in Windows it's easy: executables have an .exe extension) and where is it located? I've been browsing my hard disk for a while but don't really know where to look.
