Almost all games default to Korea region is use "Default" for emulator region setting

[ghost]

If you set the region to "Default" in the emulator under general settings, most games will end up Korea region. Many others are hard locked to the wrong region (greyed out when running the game).

For Naomi games, the region setting means the following: Japan: Japan USA: USA Europe: Export Default: Korea

In most cases the ROM indicates which regions it supports. So Flycast will switch to a supported region if the selected one isn't supported. It will select the first supported region in this order: USA, Export, Japan, Korea.

It looks like this isn't working for sgdrvsim but it's not even a game so it's not surprising. Use Japan for this one.

[ghost]

Okay but why Korea for games clearly marked as other regions? Something is wrong with that. Marvel vs Capcom 2 defaults to Korea for the mvsc2u romset which is clearly american only.

[ghost]

To add to my last comment, the entire Initial D series is messed up too. Japan games default to Export, and the actual Export editions default to Korea. Do you understand what I am getting at?

[ghost]

I dunno, not for nothing, but you seem like a lazy asshole full of excuses why you can't fix obviously broken shit yet the masses sing your praises and well I get it. They're too stupid to care enough. Thanks for blocking my last 4 legit bug reports for no reason. Now I actually gave you a real reason to ban me you slimy little prick. Bye.
