I've noticed that there is no vsync patch for or executable English file (like all the past Eng. patches, not thcrap) for DDC.
Since I've started playing with the vsync patch (man am i glad i found it, kinda amazing) DDC is unplayable. I know that the person who made all the vsync patches has been inactive since 2011 (hasn't posted on his twitter since then), but maybe someone on this forum might be able to fix that?
Also, the only English patch for DDC available right now is thcrap. It works just fine, but its a bit unconventional and its not possible to use with a vpatch (as far as i know, maybe someone will find a workaround or NL will fix that).
