The patch was built off a specific iso rip. There appears to be some differences between all the rips circulating around, and this can cause issues with the patch. 2 things:
- You'll want to look around and try a few rips of the USA version. the one I used should be the most common USA version rip.
- additionally, you'll want to turn off checksum validation in the patcher settings. Sometimes, even with the correct rip, the validation step still fails due to Windows changing the metadata on the file when you download it. With checksum validation turned off the patcher will never fail, but if you still have the wrong base iso it will crash in dolphin almost instantly.
