I'm not comfortable with using the twilight hack's third slot because 1) I vaguely remember someone important recommending not doing as this as it can cause some problems. 2) I'm afraid of accidentally overwriting the actual twilight hack. Then, I'll have to transfer the twilight hack again and it'll kill my gameplay save. (something similar happened before, i was helping my brother out on his early game save then accidentally saved it over my one, which was near the end)
So as you can see, I'm paranoid, so the third slot is out of the question. Back to the original problem, is it possible? I opened the iso in hex workshop and found the title id at the top, but i searched for it again and found several other instances. Do I have to change all of them? or is there an option in trucha?
