Oh yeah, the SyncOffset is a small feature I added to give players the ability to fine-tune their playback for better synchronization with the game. It’s used exclusively in the integration part of the mod.
I implemented it because, in my case, sending the play command with a 350ms delay provided the best results. However, this might not be ideal for everyone, as the optimal delay could vary depending on network or device. So I made a configurable option that is read and applied in kag.tag_ext/kag.tag.js:
I placed it in “EdiConfig.json” because it was a convenient, pre-existing file located outside of any archived patch components, making it easy to modify.
