I did a search on the forum and was surprised to see that no one has mentioned the MSU1 chip. I just ordered my copy of the SD2SNES (Flash Cart) and am waiting for it to arrive with anticipation. For those who don't know the MSU1 was a "chip" that was developed to give the SNES the ability to act as if it had a CD-ROM attached to it. With the fallout with Sony for the Nintendo Playstation and then with the canning of the project with Phillips all together we never got to see what the SNES could have done in this area.
Sure not much has been done as of yet with this technology, but it really intrigues me.
One example that I'm excited to try out is to play Road Avenger on the SNES which was one of my favorite FMV games on the Sega CD.
Another person has figured out how to update A Link to the Past to have CD audio and FMV sequences throughout the game.
There is also a demo of a new Super Mario game that someone was working on just to show off some of the enhancements.
Anyway... I thought I'd drop some info on the forums since I had not yet seen anything here.
