[SJ]nailz, the patch is so that an application, like SH3, can use memory greater than 2Gb, so naturally nothing else is required for 64 bit system to work, BUT it can be used in 32 bit XP with the /3Gb switch added to the boot.ini file, this will allow the application to use 3Gb instead of 2Gb, HOWEVER, although SH3 will now run other applications are effected by this switch causing stuttering, lockups etc, this is what I found so I don't use the patch!
