im not really sure what this tool is for. what i can see in forums is that lets you have more than 4gb ram, and lets you fix some 32 bits apps when running in 64 bits (arch=i386 -force64)

there is a c file that contains this in the header
*
* instruction length decoder (written by kaitek, modified by mercurysquad)
* voodoo xnu kernel
*
* based on code from AntiHookExec 1.00, Copyright (c) 2004 Chew Keong TAN
* opcode tables based on documentation from http://www.sandpile.org/
*
* todo: * support for instruction set extensions newer than SSSE3
* * verify that VT instructions are correctly decoded
* AnV - Added better opcode + SSE4.1 + SSE4.2 support
*/
also, i found 2 versions of the same tool. both with the same header but different size

one doubt: if you path those files () with this tool, does it lets you start with arch=x86_64 with a 10.6.8 legacy kernel?

best regards
