什么是 PPC?如何使用它来制作 Xbox 重启程序?

所以我一直对一种称为 jtag 的改进型 xbox 360 感兴趣。显然,对微软实施的一些系统检查,他们无法再连接到 Xbox Live,我想尝试构建一个新的重启程序。 首先,如果有人对如何去做或开始有任何想法,那就太棒了。

其次(这是我的主要问题),什么是 PPC 以及我如何学习对其进行“逆向工程”? 我正在关注本教程: http://www.thetechgame.com/Forums/ viewtopic/t=1086504.html 我想知道如何去做。我假设到目前为止我已经完成了所有事情,我已经在 IDA 中打开了正确的文件,并且我想开始它,但我真的不知道如何做。

So I've always been interested in a type of modified xbox 360 called a jtag. Apparently do to some system checks implemented by microsoft they can no longer connect to xbox live and I want to give building a new rebooter a try.
First off, if anyone has any ideas on how to go about doing this or getting started, that would be awesome.

Secondly (this is my main question), what's PPC and how do I learn to "reverse engineer" it?
I'm following this tutorial: http://www.thetechgame.com/Forums/viewtopic/t=1086504.html and I want to know how to go about doing it. I'm assuming I've done everything right so far, I've opened up the right files in IDA and I want to start in on it, but I don't really know how.

PPC(PowerPC)是一种CPU架构和指令集,你可以在网上找到参考。你提到了JTAG,JTAG不是Xbox专用的技术,它是一种通用的硬件调试标准。

您听起来好像从未进行过低级开发或逆向工程,所以我警告您,您可能远远超出了您的能力范围。不过,话虽如此,以下几点应该可以帮助您入门:

  • Xbox 运行 PowerPC 系列处理器中的 CPU。它们的工作方式是从内存中读取代码并执行该代码。 PowerPC 只是指代码采用的格式、支持哪些指令并描述其一般行为。
  • 由于您谈论的是 JTAG,因此您可能需要物理打开 Xbox,找到一些 JTAG 工具并将引线焊接到它。 您可能会损坏您的 Xbox
  • 谷歌搜索“软件逆向工程”应该可以帮助您入门,但不要指望一夜之间就能学会它,因为这是一个非常深入和技术性的主题。

PPC (PowerPC) is a CPU architecture and instruction set, the reference to which you can find online. You mentioned JTAG, JTAG isn't a Xbox-specific technology, it's a common hardware debugging standard.

You sound like you've never done low-level development or reverse engineering, so I'm warning you that you may be way over your head. However, having said that, the following few points should get you started:

  • Xbox runs a CPU that's in PowerPC family of processors. They work by reading code from memory, and executing that code. PowerPC just refers to the format that code takes, what instructions are supported and describes its general behavior.
  • Since you're talking about JTAG, you might need to physically open your Xbox, find some JTAG tools and solder leads to it. You will probably break your Xbox.
  • Googling for "software reverse engineering" should get you started, but don't expect to learn this overnight as it's a very deep and technical topic.
