While opening the archives for a bunch of patches I've not bothered to patch and load onto my various flash carts, I've run into an issue with opening up two translation archives, for The Quest of Ki and Konami Wai Wai World. Both of the rar archives cause an error message:
"A failure has occurred.
The structure of the archive is damaged."
It's not an issue with the file format, as some other rars in the same batch of patches expanded just fine. Any ideas/suggestions would be much appreciated.
