DDR but not

[GodsLeftNut]

I was woundering if you guys could help with some concepts of the ddr game. I need a way to import lots of music, but without making the file size huge. I also need a way for the game to stop when that song is done. Also i was having a lot of trouble figuring how ffr made the arrows go with the beat...i cant seem to figure that one out.

Oh and if you think im taking ddr im not...im going to add my own twist to it that ddr or ffr dont have.

Thanks in advance.
