60 fps games transformed into 30 fps games?

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

This can only be done manually via mods.

Ok, but with which software do we create mods?
Are there any tutorials ?

You should try a dedicated Discord or forum about modding, it’s not a simple process.

I don’t find the modding forum on discord. Do you have a link?
