Here's an interesting file.
It attempts to simulate the low framerate days using a lot of stops.

:hea: Is also an attempt to simulate days in which the step artists were experimenting with which patterns they use, by using some pretty turny patterns. It's all fully crossoverable, with a bit of thought. Also, yes I actually do intend players to go sideways at beats 149 and 165, but if you choose the correct foot to start on, you don't need to. If you went sideways earlier, the ending should make more sense.

:sta: Is an attempt to simulate the 4th heavy stompfests that were some of the old basic and difficult charts, too. This is the kind of thing that would be overplayed at an arcade and people would do the jumps at the end as spins.

I was originally going to have the graphics all replaced with 3rdmix graphics but I guess just the judgment is fine.
The lua files do some other uhh.. "Things" to the file to make it feel more authentic (don't worry, it resets everything when the song ends)
Replaced graphics and other lua will not work on SM3.9, but the file will still be playable.
