-stretch(x/y) x Stretch to fill surface on x or y axis(fullscreen, only with OpenGL).\n\
-efx(fs) x Enable special effects. Logically OR the following together:\n\
1 = scanlines(for yscale>=2).\n\
2 = TV blur(for bpp of 16 or 32).\n\
-fs x Select full screen mode if x is non zero.\n\
-connect s Connect to server 's' for TCP/IP network play.\n\
