I am currently trying to extract a pokemon alpha sapphire rom in order to randomize it, but I keep getting an error during the extraction process. This error is strange since I have was able to extract the rom earlier and I was able to extract a Y rom. I tried to download a new rom to fix the issue, but it didn't seem to help. I will place the error code below. If I can get any assistance, that would be very helpful.
