The build files exist and you can specifically request that I burn the VOB files onto two DVDs, for you to burn your own dual layer copy. However, this is unnecessary and not necessarily recommended.
I know that you, segaflip, will be posting this on the newsgroups or whatever, so the dual layer version might be fun to post there, but yeah, it's not necessary in the least.
I don't want people coming to me asking for a dual layer version.
