open data.js in text editor..scroll to end of json string
and after window size(480,640(in my case))
[quote:2gduzpye]"media/",false,480,640, 4, true,true,true,"1.0.0.0",true,false,4,1,26,false,true,1,true,"New project",0,[]]}
there is a number for the Fullscreen scaling (0 or 1 | 2 | 3 | 4 | 5 ).....I think the number 3 is for "Scale outer"
I really don't know... is this the only place that determines scaling..
I've never tried this before...and..... I'm too lazy to try it now(to upload game..and test..)..
so...
as Twin Blazar said re-export is best solution...
