SDL\_VIDEO\_CENTERED=1 is a env variable

not sure what you mean

I think this code is nothing to do with gameshell self, you can use it and the DOSBox svn window should be in the center

yep Im using DOSBox svn.  
but with surface option window is not being in the center…  
surface mod is faster than overlay… but if I change to fullscreen  
then overlay mod is only choice…

then I guess DosBox svn surface mod should do something to deal the ` SDL_VIDEO_CENTERED=1`

SDL self won’t auto deal with the `SDL_VIDEO_CENTERED=1`
