I'm trying to find a way to unlock the Echo Visor in Metroid Prime 2 at the beginning of the game.
So far I've considered trying to find an Ocarina code to unlock the item or manually editing the save file. Either solution is good.
Finding the Ocarina code, I have no idea how to go about. I'm assuming I'd need to look at the memory in some way, and given I've not got a USB Gecko I can only assume I have to use Dolphin or some other emulator to examine the memory. And even if I reached that point, I wouldn't know what to do.
Manually editing the save file, I also am unsure how to go about. I think the Wii save files are encrypted, so is there a way to encrypt and decrypt the save files so I find which piece of data determines whether or not you have the echo visor and then am able to change that value in a different save file?
