I need to make a backup of Tenchu 2 for PAL on PSX. (I'm in Australia if that changes anything). Tenchu 2 is neither on the Unprotected Games list or the Protected Games list, but it's fairly recent so I'm assuming it's protected.
In the PSX Patches page under T it has about 5 or 6 patches for Tenchu 2, but none of them seem to be exactly what I'm looking for. If one of them is, which one do I need exactly to make a backup?
