Korean version of Super Mario Galaxy 2 doesn't boot

[Psycho]

Yes, I read the wiki and followed "Language Region Mismatch"
and it does indeed help a lot of Korean and Japanese isos but not this one specifically

Tested on Dolphin 5.0-7516
Qt backend
GTX 1070
DX11

What exactly happens when you try to boot it? (Black screen? Error message?) And have you verified that you have an accurate dump?

[Psycho]

Yeah, the iso wasn't tampered. It just black screens on startup. Like, if you have a Japanese game that needed this exact same procedure and intentionally set it to English resulting into a black screen. Exact scenario, except I set it to Korean and it didn't solve the problem. Galaxy 1 has the exact same region checking built into the game and that worked just fine.

It's still worth double-checking - a number of issues have been due to ISOs getting corrupted silently and nobody noticing until they happen to hit a specific area/something in dolphin changes that now relies on the corrupted data. It seems weirdly common at times, considering how modern computers should be pretty good at managing the data.

You should be able to compute an md5 checksum from dolphin - right-click on the game, click properties, go to the info tab and there's a "compute checksum" button. That should take a bit of time, then fill out the corresponding box with a load of hex characters. I tend to use google to search for that - if there's not an exact match from gametdb then there's a very good chance the iso has been corrupted, and needs to be re-dumped.

Note, transforming the iso in any lossy way changes the checksum, so makes the above invalid, so it may not be useful if you've converted it to a gcz compressed form, or wbfs or similar.

That won't work in this case, unfortunately. There's no hash on gametdb.com for the Korean version of this game, and as far as I know, it's not on on redump.org either.

Most of the Korean ISOs are tampered with - unless you've absolutely dumped it yourself, there's a good chance it requires some kind of cIOS.

For Wii ISOs you can use Dolphin's Check Partition Integrity Feature, which I personally think it's more reliable than the MD5 hashes. Right-click the game in Dolphin => File System tab => Right-click Partition 0 => Check Partition Integrity. Repeat the process with other partitions if you ISO has more than one...

This is good to do, but keep in mind that there are problems that it won't catch, such as if the IOS version field has been modified like JMC described.

Just dropping by to confirm that I tried Dolphin's Check Partition Integrity Feature and no errors were found.

Is there anywhere I can even order Korean Wii games to dump them and get a comparison hash?
