The awesome thing about the current generation of consoles is that they're much closer to modern computers than the 8, 16 or even 32-bit days. This means that, programming wise, they tend to be much easier to hack. We've already seen fan translations for Tales of Innocence and Soma Bringer picking up the slack where Namco-Bandai and Nintendo have failed. Well, there's now an English translation for Zero: Tsukihami no Kamen, going under the name Fatal Frame 4: Mask of the Lunar Eclipse. What's more, you don't have to resort to piracy to get the patch working - I've heard it won't even worked with pirated versions, although there appears to be torrents around that suggest otherwise.
Assuming you want to play the game legitimately, you'll need a copy of the game. - the problem is, finding it.
Zero: Tsukihami no Kamen is a year and a half old now, having been released in July 2008. Most import retailers no longer carry it, or are still carrying it at retail price. My eyebrows furrow when stuff like this happens, because while prices can plummet in the Japanese marketplace pretty quickly, the importers usually never drop their prices unless it's a huge failure or it gets a reprint, so new titles that can be found on the streets for a few thousand yen are still being sold to the rest of the world for the equivalent of $75. It's good to be aware when you're being gouged!
So I checked with Amazon Japan and:
Yeah, it's still pretty expensive over there, too. Of course, like other marketplaces, Amazon isn't the be-all-end-all of price gauging, but it certainly hasn't dropped all that much, either. The cheapest used copy there is 4900 yen or about $55. I browser around a bit and all of the other internet retailers I found still listed it for a bit under the retail price, about 6200 for this one here. (Does HMV Japan ship outside the country?) All of the other Zero games can be found cheap in Japan since they all got reprints, but given all of the drama surrounding this release, that may not be the case. In other words, if you're curious, you might want to grab this soon before it completely disappears.
