No. Any console of any region will be able to play the game in English.
No. However, a full translation patch of the PS3 Tales of Graces F Demo has been released and is available for download.
At the moment the Wii version of the patch is our priority; it will be completed and released before the PS3 translation. There is currently no ETA.
A console of any region and a retail Japanese disc of Tales of Graces or Tales of Graces F. Either version of the Wii game will work, as will the Asian version of the PS3 game. See the Wii or PS3 versions of this question for specific homebrew requirements.
No. The translation will only work with Riivolution/R3volution, and will not work with backups, ISOs, or emulators. Buy the game.
Check the links in the left sidebar.
You will need to use Riivolution to run it, see this thread for details.
We cannot guarantee that the patch will work on any firmware version later than 3.55. We also suggest that you avoid trying any sort of "CFW" in the meantime; instructions will be posted when the patch is released.
The translated Tales of Graces F Demo was released before recent PS3 hacking advancements, and so it requires firmware 3.41, a USB drive, and a special USB device. We do not recommend any of the commercial devices such as the PSJailbreak as they are usually not flashable and will be incompatible with the patch. A device such as the Teensy is cheap and perfect for the job. A number of ports for common electronic devices are available.
The game disc will update your PS3 to 3.50 if you are on 3.41. This will allow you to play the game normally (the PS3 is a region free console).
There is no harm in updating your PS3 with the disc, though you will lose the ability to play the English demo patch.
