Here's an issue: Since I'm still in October data (2024101500), adding some 4 letter song IDs in the gamemdx.dll will not work just like Rabbit hole (of course a new data due to procrastination is needed to update this). Although the ssqs were clean, but sadly separated due to BPM changes.
What I did was creating a backup of their charts from stvi_3 and stvi_5 (came from GP files) to rename them to work....separately.
If ever a clean data of 2024112700 - 2025012803 came up, hopefully will be a no problem for us.
