I don't have any mockups, maybe a basic text under the title would work fine. I honestly don't know what Zouringen means, we need an actual translator to show up and tell us. It could be a name, but of a boss, or a location?
Also, there's this one Famicom game called "Kyoryu Sentai ZyuRanger" (Kyouryuu Sentai Juuranger according to GoodNES) that had a translation for it. If the characters appear familiar, that would be because this was based on the Sentai series that eventually became Mighty Morphin Power Rangers. So if you could, perhaps you could edit the title logo to the MMPR one? Of course, the original title theme isn't the MMPR one, and would be rather weird without it.

Lucky for you, the Chinese made a bootlegged version of the SNES MMPR game, so you could yank (and redraw) the logo from that one. This is a suggestion more than anything, so thanks for reading!
