Update to v106r129 release.
byuu says: fixed the pitch/speed of the VRC7, and added a 2280hz lowpass filter to match hardware a bit more (it's kind of hacked in, but it works.) forgot to set the echo buffer disable flag on the SNES DSP, which was breaking SNES games, so that's fixed. started emulating the famicom disk system. so far just the icarus BIOS + FDS disk imports (won't handle multi-disk merged ROMs yet), the basic PCB mapping of PRG-ROM+RAM and CHR-RAM, some MMIO registers, FDS timer IRQs, and the GUI connections to connect a disk (marked hot swappable.) I need more info on the low-level details of how the ram adaper talks to the disk drive to proceed further. But it's a start.
