I'm trying to get a randomizer working for oras, I've tried running the .romfs and .code through hans both on my outdated o3ds and updated n3ds but nothing seems to be working. I'm not getting the rainbow line on the left side of the screen, it just gives me an error message saying "invalidated icache". I was reading through other forums with this same problem, but they all said to update hans and it hasn't worked for me. What does "invalidated icache" mean and how can I fix this?
