Update to bsnes v042r04? release.

New WIP. Copy-paste:
> Working on SA-1, still a long way to go. Fixed a bug where I was
> clearing MA after multiplication / cumulative sum when I wasn't
> supposed to. Fixes Kirby 3 Pop Star scene.

> Added normal DMA, along with full support for DPRIO (allowing DMA to
> run alongside the SA-1 CPU) and blocking of invalid transfer types /
> modes. This fixes sprites in Marvelous.

> Also added BW-RAM bitmap mirroring to $[60-6f]:[0000-ffff], proper
> mapping for the bitmap mode to the $[00-3f|80-bf]:[6000-7fff]
> regions, variable-length bit read data port, and I now at least
> cache the register settings for IRQs (though I still do nothing with
> them.)

> I added support for BW-RAM and I-RAM write protection, but when it's
> enabled, most games will no longer load. So I'm forced to leave that
> off for now. Maybe the protection didn't actually work on the real
> hardware? Hmm ...

> No idea what the bitmap registers $2240-$224f are for, and I don't
> see how it's supposed to be possible to trigger IRQs as needed by
> Super Mario RPG and Parodius. But at least three of five games
> should now be fully playable with no issues. Speed remains the same
> as yesterday. No hit for the SA-1 CPU+DMA simultaneous transfer mode
> support.

Can always try it and see what happens ... after I get some sleep :D
