I'd suggest making a new shortcut to use only when playing, as this isn't something you'd want to use all the time.how do you open it with chromes
1) Make a new Chrome shortcut
2) right-click > properties
3) in the target field, at the end, after the last quotation mark, add a space and then: --allow-file-access-from-files
4) Click apply
That should do the trick. You may have to copy the file:/// url to the new window.
