Bell has released a new YAOSM firmware, 1.9 and a beta release. The major change in this firmware is the Super Mario Galaxy fix. The stable release of this firmware will work with almost any chip, but it lacks the Gamecube audio fix. A beta build was also released with the audio fix, but it will not fit on a PIC 12F629. Grab the stable release at its release thread here. The beta w/ the GCN audiofix and its release thread is right here. Make sure to read the thread to find out if your chip can handle the beta.
