Hey guys sorry this is taking so long for me to get back to you, my internet at home keeps disconnecting after uploading ~30MB. I really hoped that It would be fixed today, so stay tuned, if I dont get it up at my place, I will try elsewhere.
CP: The audio is WAY off on the DS-X. The R4 is a very fast cart, while the DSX is quite slow. The result is the songs FINISHING and having a good 45 seconds before the sprites finish their dance on the opening song. I'm going to try having the sprite action scripts buffer things a bit before the song starts, that may help as well. Its important to get this right on a variety of platforms. While I agree that I love the HQ audio, some cards just cant handle it correctly. Bit rate may have to be sacreficed in order to allow bandwidth for the action scripts.
Edit: Will someone post an SRAM file (and state what card the file came from) with all of the cutscenes unlocked in encore mode, it would be VERY useful for all involved on the testing.
