Zero: Tsukihami no Kamen

Zero: Tsukihami no Kamen (零〜月蝕の仮面〜, Zero: Mask of the Lunar Eclipse), known in the states as Fatal Frame IV: Mask of the Lunar Eclipse is a survival-horror video game developed by Tecmo and Grasshopper Manufacture and published only in Japan by Nintendo for the Wii video game console. It is the fourth game in the Fatal Frame series and the first of two on the Wii, followed by a re-release of Fatal Frame II.

Incorrectly Patched Disc Image Not Starting
If you have patched the game with a patch such as the English translation patch, the region data of the game might be incorrect, depending on how you've applied the patch. If that is the case, Dolphin and newer will be unable to start the game, getting stuck on a black screen. The region data can be corrected by opening the ISO file in a hex editor and changing the byte at 0x4E003 to 00.

Corrupt Font With English Patch
When using the English patch, certain text may appear distorted or glitched. To fix this, make sure GPU Texture Decoding is enabled. Anisotropic filtering is required to be greater than 1x for the text to appear correctly when playing at native resolution. Otherwise, simply turn up the resolution and the text will appear normal. This works on OpenGL and Direct 3D, but not as well with Vulkan. This problem is only present when using the English patch. The original Japanese font always appears normally.
