Anyone ever hear of this MSU-1 thingy? Basically, the creator of Bsnes/Higan created this "Media Streaming Unit", or MSU, which...
"allows the SNES to have 4 GB of storage space and CD quality Stereo Audio. It can be used for every SNES games, but is so far only emulated by bsnes, and supported by future SNES flashcart, sd2snes."
It seems to me, that this could have been what the Snes CD would have given us. While not exactly authentic, it's still interesting to see how cd quality music can affect, change, alter, and potentially even enhance the games we all know & love. It works on real hardware via the SD2Snes, and obviously in Bsnes too. Check it out:
