Update to higan and icarus v095r15 release.
r13 and r14 weren't posted as individual releases, but their changelogs
were posted.
byuu says about r13:
I'm not going to be posting WIPs for r13 and above for a while.
The reason is that I'm working on the major manifest overhaul I've
discussed previously on the icarus subforum.
I'm recreating my boards database from scratch using the map files
and the new map analyzer. The only games that will load are ones
I've created board definitions for, and updated
sfc/cartridge/markup.cpp to parse. Once I've finished all the
boards, then I'll update the heuristics.
Then finally, I'll sync the syntax changes over to the fc, gb, gba
cores.
Once that's done, I'll start posting WIPs again, along with a new
build of icarus.
But I'll still post changelogs as I work through things.
Changelog (r13):
- preservation: created new database-builder tool (merges
region-specific databases with boards)
- icarus: support new, external database format
(~/.config/icarus/Database/(Super Famicom.bml, ...)
- added 1A3B-(10,11,12); 1A3B-20
byuu says about r14:
r14 work:
I successfully created mappings for every board used in the US set.
I also updated icarus' heuristics to use the new mappings, and
created ones there for the boards that are only in the JP set.
Then I patched icarus to support pulling games out of the database
when it's used on a game folder to generate a manifest file.
Then I updated a lot of code in higan/sfc to support the new mapping
syntax. sfc/cartridge/markup.cpp is about half the size it used to
be with the new mappings, and I was able to kill off both map/id and
map/select entirely.
Then I updated all four emulated systems (and both subsystems) to
use "board" as the root node, and harmonized their syntax (made them
all more consistent with each other.)
Then I added a manifest viewer to the tools window+menu. It's kind
of an advanced user feature, but oh well. No reason to coddle people
when the feature is very useful for developers. The viewer will show
all manifests in order when you load multi-cart games as well.
Still not going to call any syntax 100% done right now, but
thankfully with the new manifest-free folders, nobody will have to
do anything to use the new format. Just download the new version and
go.
The Super Famicom Event stuff is currently broken (CC92/PF94
boards). That's gonna be fun to support.
byuu says about r15:
EDIT: small bug in icarus with heuristics. Edit
core/super-famicom.cpp line 27:
if(/*auto*/ markup = cartridge.markup) {
Gotta remove that "auto" so that it returns valid markup.
Resolved the final concerns I had with the new manifest format.
Right now there are two things that are definitely broken: MCC (BS-X
Town cart) and Event (CC '92 and PF'94).
And there are a few things that are untested: SPC7110, EpsonRTC,
SharpRTC, SDD1+RAM, SufamiTurbo, BS-X slotted carts.

Update to v089r17 release.
byuu says:
This implements the spec from the XML part 3 thread:
http://board.byuu.org/viewtopic.php?f=16&t=2998
It's also propagated the changes to nall and purify, so you can test
this one.
This is basically it, after years of effort I feel I finally have
a fully consistent and logical XML board format.
The only things left to change will be: modifications if emulation turns
out to be incorrect (eg we missed some MMIO mirrors, or mirrored too
much), and new additions.
And of course, I'm giving it a bit of time for good arguments against
the format.
Other than that, this release removes linear_vector and pointer_vector,
as vector is better than linear_vector and I've never used
pointer_vector.
vector also gets move(), which is a way to use move-semantics across
types. It lets you steal the underlying memory pool, effectively
destroying the vector without a copy.
This works really nicely with the move for read() functions to return
vector<uint8> instead of taking (uint8_t*&, unsigned&) parameters.

Update to v080r01 release.
byuu says:
There was one unfortunate aspect of the S-DD1 module: you had to give it
the DMA length and a target buffer, and it would do the entire
decompression at once. Real hardware would work by streaming the data
byte by byte. So with that, I went ahead and rewrote the code to handle
byte-based streaming.
This WIP is an important milestone for me personally. Up until now,
bsnes has always had code that was directly copy-pasted from other
authors. With all of the DSP and Cx4 chips rewritten in LLE, and the
SPC7110 algorithm already ported over from C, and archive decompression
code removed for a long time, the S-DD1 was the only module left like
this. It's obviously not that big of a deal. The code is basically still
a copy of the original. S-DD1 decomp from Andreas Naive, SPC7110 decomp
from neviksti, and S-DSP from blargg. And the rest of the emulator is of
course only possible because of code and research before it, although
everything else has no resemblance at all to code before it. The main
advantage, really, is absolute code consistency. I always use the same
variant of K&R, for instance. I dunno, I guess I just never really liked
the "Build-a-Bear Workshop" style of emulators, like is so prominent in
the Genesis scene: "My new Genesis emu (uses Starscream/Musashi 68K
core, Marat Fayzullin's Z80 core, YM2612 core from Game_Music_Emu, VDP
core from Gens, SVP core from picodrive)", sorry, but you wrote
a front-end, not an emulator :/
I also updated the SPC7110 decompression module: I merged the class
inside the SPC7110 class (not sure why it was separate before), and
replaced the morton lookup tables with for-loops. The morton tables were
added to be a tiny bit faster when I was more interested in speed than
code clarity. It may be a tiny bit slower (or faster due to less L2
cache usage), but you won't even notice an FPS drop, and it cuts out
a good chunk of code and some tables. Lastly, I added pinput_poll() to
video_refresh(). Forgot to remove Interface::input_poll() from the C++
side, will have to do that later.
