Luigi's Mansion Dark Moon progress?

I have tried this game again after about 6 months, it seems like some slight progress has been made! Getting about 30% speed when before it was less than 10.

I was wondering if the crashes were still happening when facing the first ghosts? Or if anybody had been able to gain better speeds somehow?

I remember some time ago there was an unofficial build going around with this option called “FMV Hack AddTicks”, or something along those lines that actually made the game run at almost full speed, albeit with completely messed up audio… Is this an option that is possible to access in the official build?

Many thanks!
