Update to v106r69 release.

The biggest change was improving WonderSwan emulation. With help from
trap15, I tracked down a bug where I was checking the wrong bit for
reverse DMA transfers. Then I also emulated VTOTAL to support variable
refresh rate. Then I improved HyperVoice emulation which should be
unsigned samples in three of four modes. That got Fire Lancer running
great. I also rewrote the disassembler. The old one disassembled many
instructions completely wrong, and deviated too much from any known x86
syntax. I also emulated some of the quirks of the V30 (two-byte POP into
registers fails, SALC is just XLAT mirrored, etc) which probably don't
matter unless someone tries to run code to verify it's a NEC CPU and not
an Intel CPU, but hey, why not?

I also put more work into the MSX skeleton, but it's still just a
skeleton with no real emulation yet.
