Update: v0.5c (See http://maxxuss.hotbox.ru/patch.html for the reason of v0.5c)


This is the 5th version (v0.5b) of my Patch solution.


It's now SSE3->SSE2 and Anti-TPM all-in-one:


1) SSE3->SSE2 solution: Mac OS X SSE3->SSE2 Runtime Patcher & Emulator, directly in the kernel



2) Anti-TPM solution: Rosetta Patch (oah750/oah750d), which circumvents the TPM copy-protection in a clean way.


You can install!


The complete download is available as a compressed ISO file "Maxxuss-SSE2-AntiTPM-Patches-v0.5c.iso" (~ 12 MB for RAR, ~ 17 MB for ZIP) at these locations:


RAR Archive: mytempdir.com
RAR Archive: www.xs4all.nl/~bertwill/osx86/
RAR Archive: rapidshare.de
ZIP Archive: mytempdir.com
ZIP Archive: rapidshare.de
There is also a standalone download of the Anti-TPM patch available for those with a SSE3 CPU (~ 900 KB for RAR, ~ 1900 KB for ZIP):

Use the included script "install.sh" to install the files (with a backup), and/or to restore the original files. The installer also prints a lot of information.


Description for SSE3->SSE2 Solution:


This is a hybrid solution for running Mac OS X/Intel and especially Rosetta under SSE2-enabled CPUs. You don't need SSE3 anymore.


Technical Info:


It is hybrid, since it uses a three-fold approach:


1) Rosetta's SSE3 instructions (MOVDDUP) are patched at runtime to more-or-less equivalent SSE2 instructions (MOVQ).


2) Relevant system files (CoreGraphics, oah750, libSystem.B.dylib) are pre-patched to enable fast execution speed (emulation is always slow!). I replaced SSE3 instructions (FISTT) with their more-or-less equivalent SSE2 analog (FIST).


3) SSE3 instructions, which raise an "Illegal Instruction" exception are specially treated:


3.1) FISTT instructions are 100% emulated by the kernel.
3.2) All other (unknown) SSE3 instructions are skipped.


Please note 3.1): This is rather important, since 2) "Pre-patched files" did not contain all files with SSE3 FISTT instructions in it. So 3.1) ensures that these will be handled, too.


Description for Anti-TPM Solution:


This solution contains two patched files, oah750 and oah750d. The patch suppresses the TPM-related checks which are built into Rosetta (file "oah750") and it's background process "oah750d". By installing this patch, there won't be any Rosetta-related crashes anymore, hopefully.


Technical Info:


oah750d is responsible for caching transformed code, so it is really required for executing PPC-native code. Another task of oah750d is TPM related verifications on behalf of a executing Rosetta-powered program, e.g. ATSServer or iTunes. I've put the main part of my patch into the oah750 file, so that it will not call oah750d for TPM-related requests anymore.


What's in the ISO:
- Readme.rtf

- install.sh (Open with your Mac OS X' Terminal.app)


- Mach kernel with SSE3 emulation for CPUs with SSE2

- SSE3 System files: CoreGraphics, libSystem.B.dylib

- SSE2-prepatched System files: CoreGraphics, libSystem.B.dylib

- TPM-patched SSE3 file "oah750"
- TPM-patched SSE2-prepatch file "oah750"
- TPM-patched file "oah750d"


How to Install:
- Burn CD or simply mount it in your Mac OS X system

- Open Terminal.app

- Use "cd" command to get into the CD, e.g. "cd /Volumes/MAXXUSS0.5b/"
- Type "sudo ./install.sh"
- Follow the instructions

- Restart Mac OS X

- Enjoy.


How to Uninstall:
- As in "How to Install", but select "r" (Restore) when asked.
- Note: you can also uninstall in single user moder (-s at boot prompt). To do this, you should copy the install.sh script to your harddrive.


What's new in v0.5 (since v0.4)
- Bug fixes for SSE3->SSE2: No more WindowServer crashes with SSE3-enabled system files.
- Completely new patch for Anti-TPM: no more crashes in oah750d, ATSServer, iTunesHelper, iTunes etc.; also: applications now quit properly without crashes.
- I have also fine-tuned the installation process. I hope you like it.


Credits:
- Thanks for all members and admins of osx86project for testing, feedback, and file mirrors!
- Thanks to adilson for the first working patch of oah750d.
- Thanks to omni for a refinement of adilson's patch.


Please spread the word, and the files!


Comments/Feedbacks are very welcome!!!!!
What's working and what's not?????
