Hakuouki help

I do not know if there's been a topic for this made because I could not find anything for my certain card. If there is one, please link me to it. :)Anyway, I'm having problems running the game Hakuouki.
I am using an r4ultra card, v1.55 firmware, and everytime I play the game it freezes on a grey screen. I tried using the things that have been stated. Something about a TTmenu and YSmenu or something but it doesn't work for me. I tried searching for a patch but I cannot find any whatsoever.Can anybody help me play this game? I really want to play it...
Thank you!!~ :D

i have the same problem too! but its with a white screen....
i even tried using my friends r4 files yet it still doesnt work
i read someones comment for the rom that had the same thing too. does anyone know how to fix this?
