Force Expert Staff Ghosts to Load on Specific Track [Diamond]

Forces the expert staff ghosts to load on the tracks designated by their filename, negating the need to have to manually change this in hex. This code is required to bypass any checksum error that may occur: https://mkwii.com/showthread.php?tid=1600.
Changing the source could allow you to change the track order, as well as the types of ghosts that get their track ids overwritten.

I'm really impressed with your recent work. Keep it up!

So how does this work. Will this allow staff ghosts on LE Code or CT Code custom tracks
