之前曾有一名匿名开发员公布了Vita上psp模拟器的flash dump,而昨天wololo更新了博客，说明论坛会员wth也取得了vita上psp模拟器的核心漏洞，并公布了vita 1.61, 1.67和1.69版本固件psp模拟器的flash dump，为黑客们的研究提供了最新的素材。
7月29日wololo博客更新——wth导出了PSP模拟器的Flash dump
（原地址http://wololo.net/2012/07/29/vit ... sp-emulator-by-wth/）
Vita: Flash dump of the psp emulator by wth
Vita：wth导出的PSP模拟器Flash dump
Wth(a.k.a. Yosh), who is known for his port of VHBL to the Everybody’s Tennis exploit earlier this year, and also for his nice yMenu for VHBL, just released a dump of the psp emulator’s flash on the Playstation Vita.
The released files contain a dump of the psp emu on Vita firmwares 1.61, 1.67, and 1.69. Wth got help from PSP scene veterans Virtuous Flame and Zer01ne in order to get a dump from each specific firmware.
Wth（又名Yosh）——他因为今年早些时候将VHBL成功移植到《大众网球》漏洞而闻名，而且他还为VHBL制作了很棒的yMenu——刚刚公布了PSV上psp模拟器的flash dump。
公布的文件包含了Vita 1.61, 1.67和1.69版本固件的psp模拟器dump。Wth从PSP破解界的老兵Virtuous Flame和Zer01ne那里得到了帮助，从而获得了每个特定版本固件的dump。
The last time such a Flash dump was released, it had been done by an anonymous developer, who later became famous by running PS1 games on the vita through the psp emulator. Wth also credits him for this release.

上次也公布了这样的一个Flash dump，它是由一位匿名开发员完成的——后来他也因为通过psp模拟器在vita上运行PS1游戏而闻名。Wth这次也做到了。
This release doesn’t mean much immediately from the end users’s point of view. It won’t magically hack your vita. But it means wth is in possession of a Kernel exploit inside the psp emulator, joining the expanding circle of people who have a full access to the psp emu inside the Vita. Somehow, this put us closer to a PSP CFW on the Vita. Also, for hackers and developers, this gives a more up-to-date dump of the flash to work with.
从终端用户的角度来说，这次的公布并没有太大的即时意义。它不会魔法般地破解你的vita。不过它意味着 wth拥有了psp模拟器内部的一个核心漏洞，加入了拥有Vita内部psp模拟器完全访问权限的那群人中——这个群体在不断地扩大着。这也以某种方式拉近了我们与Vita上PSP CFW（自制系统）的距离。而且，这也为黑客和开发员们提供了可供研究的最新flash dump。
PSP CIPHER
PSP Cipher（PSP***）
The release also includes an updated version of PSP Cipher. PSP Cipher is an alternative to PRXDecrypter, which supports potentially more files than PRX Decrypter. This tool is used, as the name implies, to decrypt PSP files, such as eboots, or files in the flash. wth’s release includes some Vita specific keys. Quoting the readme:
PSPCipher by [email protected](aka hrimfaxi).
It can decrypt PRX type 5 (0x2e5e12f0) when prxdecrypter 2.4 etc failed to handle. It’s a completely reimplemention version as mesg_led_02g.prx and memlmd_02g.prx from FW 6.20. So if you are clever to find DRM decryption key you can decrypt DRMed module with it.
The sample decrypts host0:/enc/EBOOT.BIN and save to host0:/dec/EBOOT.BIN. kbridge dir contains decryption implemention. Please see pspcipher.h to use the code.
The source is covered by GPLv3 to fight aginst Sony NPDRM.
这次公布的文件还包含了一个新版本的PSP Cipher。PSP Cipher是PRXDecrypter的一个替代品，与PRX Decrypter相比，它也许可以支持更多的文件。正如它名字所暗示的意思，这个工具是用来破解PSP文件的，例如eboots，或者是闪存里的文件。Wth公布的文件还包含了一些Vita专用的密钥。以下是引自自述文件的内容：
由[email protected](aka hrimfaxi)制作的PSPCipher
它可以破解prxdecrypter2.4等无法处理的PRX type 5（0x2e5e12f0）文件。它有一个完全重制的版本——6.20固件的mesg_led_02g.prx和memlmd_02g.prx。所以如果你足够聪明，可以找到DRM破解密钥的话，你就能用它来破解DRMed模块。
样本破解了host0:/enc/EBOOT.BIN，保存到了host0:/dec/EBOOT.BIN。kbridge dir包含了破解程序。请查看pspcipher.h来使用代码。
来源受对抗Sony NPDRM的GPLv3保护。

The legality of the released files is questionable, so I am not putting any direct link here, and it is possible our mods will start deleting all direct links to this release sometime soon (still waiting for a decision as I type this). But I’m sure anybody with a bit of google skills will be able to find the files.
本次公布文件的合法性遭受质疑，所以这儿我就不放任何直接链接了，很可能我们的现代派人士很快就会开始删除本次公布相关的所有直接链接了（在我打这段文字时，还在等待相关的决定）。不过我相信任何一个会一点google技巧的人都可以找到这些文件。
