Homebrew SM -> DsDsR song converting tool

[Shockah]

Hi, I've made in... maybe 3 hours simple program for converting StepMania songs to DsDsRevolution songs.

But StepMania songs can be played without converting in DsDsRevolution. So what's my program doing?
-converting background image to 256x192 PNG
(-converting OGGs to WAVs)
-converting WAVs or MP3s to MP3 96kbps
-deleting all unnecessary files (it leaves only SM, background and song)
