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 v093r01 release.
byuu says:
Changelog:
- added SA-1 MDR; fixes bug in SD Gundam G-Next where the main
battleship was unable to fire
- added out-of-the-box support for any BSD running Clang 3.3+ (FreeBSD
10+, notably)
- added new video shader, "Display Emulation", which changes the shader
based on the emulated system
- fixed the home button to go to your default library path
- phoenix: Windows port won't send onActivate unless an item is selected
(prevents crashing on pressing enter in file dialog)
- ruby: removed vec4 position from out Vertex {} (helps AMD cards)
- shaders: updated all shaders to use texture() instead of texture2D()
(helps AMD cards)
The "Display Emulation" option works like this: when selected, it tries
to load "<path>/Video Shaders/Emulation/<systemName>.shader/"; otherwise
it falls back to the blur shader. <path> is the usual (next to binary,
then in <config>/higan, then in /usr/share/higan, etc); and <systemName>
is "Famicom", "Super Famicom", "Game Boy", "Game Boy Color", "Game Boy
Advance"
To support BSD, I had to modify the $(platform) variable to
differentiate between Linux and BSD.
As such, the new $(platform) values are:
win -> windows
osx -> macosx
x -> linux or bsd
I am also checking uname -s instead of uname -a now. No reason to
potentially match the hostname to the wrong OS type.

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 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.

Update to v074r11 release.
byuu says:
Changelog:
- debugger compiles on all three profiles
- libsnes compiles on all three platforms (no API changes to libsnes)
- memory.cpp : namespace memory removed (wram -> cpu, apuram -> smp,
vram, oam, cgram -> ppu)
- sa1.cpp : namespace memory removed (SA-1 specific functions merged
inline to SA1::bus_read,write)
- GameBoy: added serial link support with interrupts and proper 8192hz
timing, but obviously it acts as if no other GB is connected to it
- GameBoy: added STAT OAM interrupt, and better STAT d1,d0 mode values
- UI: since Qt is dead, I've renamed the config files back to bsnes.cfg
and bsnes-geometry.cfg
- SA1: IRAM was not syncing to CPU on SA-1 side
- PPU/Accuracy and PPU/Performance needed Sprite oam renamed to Sprite
sprite; so that I could add uint8 oam[544]
- makes more sense anyway, OAM = object attribute memory, obj or
sprite are better names for Sprite rendering class
- more cleanup

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.

Changelog:
- fixed nall/path.hpp compilation issue
- fixed ruby/audio/xaudio header declaration compilation issue (again)
- cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the
file was whitespace overkill)
- added null terminator entry to nall/windows/utf8.hpp argc[] array
- nall/windows/guid.hpp uses the Windows API for generating the GUID
- this should stop all the bug reports where two nall users were
generating GUIDs at the exact same second
- fixed hiro/cocoa compilation issue with uint# types
- fixed major higan/sfc Super Game Boy audio latency issue
- fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions
- major cleanups to higan/processor/r65816 core
- merged emulation/native-mode opcodes
- use camel-case naming on memory.hpp functions
- simplify address masking code for memory.hpp functions
- simplify a few opcodes themselves (avoid redundant copies, etc)
- rename regs.* to r.* to match modern convention of other CPU cores
- removed device.order<> concept from Emulator::Interface
- cores will now do the translation to make the job of the UI easier
- fixed plurality naming of arrays in Emulator::Interface
- example: emulator.ports[p].devices[d].inputs[i]
- example: vector<Medium> media
- probably more surprises
Major show-stoppers to the next official release:
- we need to work on GB core improvements: LY=153/0 case, multiple STAT
IRQs case, GBC audio output regs, etc.
- we need to re-add software cursors for light guns (Super Scope,
Justifier)
- after the above, we need to fix the turbo button for the Super Scope
I really have no idea how I want to implement the light guns. Ideally,
we'd want it in higan/video, so we can support the NES Zapper with the
same code. But this isn't going to be easy, because only the SNES knows
when its output is interlaced, and its resolutions can vary as
{256,512}x{224,240,448,480} which requires pixel doubling that was
hard-coded to the SNES-specific behavior, but isn't appropriate to be
exposed in higan/video.

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:

byuu says:
You guys are going to hate the hell out of this one. It's twenty hours
of non-stop work, no exaggeration at all. Started at 4AM, just wrapped
up now at 8PM.
I rewrote the entire memory subsystem.
Old system:
65536 pages that map 256 bytes each
Mapping a new page overwrites old page
Granularity capped at 256 bytes minimum, requiring ST-001x to map
60:0000-00ff instead of 60:0000,0001
Classes inherit from MMIO and Memory, forcing only one mappable function
per class, and fixed names
MMIO sub-mapper inside memory: 00-3f:2000-5fff for one-byte granularity
Can dynamically change the map at run-time, MMC register settings
perform dynamic remapping
New system:
XML mapping is still based around banklo-bankhi:addrlo-addrhi, as that
shapes almost everything on the SNES very well
Internally, 2048 pages that map 8192 bytes each
Pages are vectors, scans O(n) from last to first (O(log n) would not
help, n is never > 3)
Can multi-cast writes, but not reads [for the obvious reason of: which
read do you return?]
Can map reads and writes separately
Granularity of one for entire 24-bit address range, no need for MMIO
- whatever is in XML is exactly what you get
Read/Write tables bind function callbacks, so I can have any number of
functions with any names from any classes with no inheritance (no
more uPD7725DR, uPD7725SR helpers, etc)
Less memory usage overall due to less tables [ I tried 16 million tables
and it used 2GB of RAM >_o ]
Cannot dynamically change the map at run-time, MMC read/write functions
perform address translation [worse average case speed, better worst
case speed]
Now the hate me part, functors can't beat virtual functions for speed.
There are speed penalties involved:
-4.5% on average games
-11% on SuperFX games (SFX has its own bus)
-15% on SA-1 games (SA-1 has two buses)
Of course the two that need the speed the most get the biggest hits.
I'm afraid there's really not a lot of wiggle room to boost speed back
up.
I suppose one bright spot is that we can much more easily try out
entirely new mapping systems now, since the dynamic portions have been
eliminated.

Read/Write tables bind function callbacks, so I can have any number of
functions with any names from any classes with no inheritance (no
more uPD7725DR, uPD7725SR helpers, etc)
Less memory usage overall due to less tables [ I tried 16 million tables
and it used 2GB of RAM >_o ]
Cannot dynamically change the map at run-time, MMC read/write functions
perform address translation [worse average case speed, better worst
case speed]
Now the hate me part, functors can't beat virtual functions for speed.
There are speed penalties involved:
-4.5% on average games
-11% on SuperFX games (SFX has its own bus)
-15% on SA-1 games (SA-1 has two buses)
Of course the two that need the speed the most get the biggest hits.
I'm afraid there's really not a lot of wiggle room to boost speed back
up.
I suppose one bright spot is that we can much more easily try out
entirely new mapping systems now, since the dynamic portions have been
eliminated.

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 v074r03 release.
byuu says:
You guys are going to hate the hell out of this one. It's twenty hours
of non-stop work, no exaggeration at all. Started at 4AM, just wrapped
up now at 8PM.
I rewrote the entire memory subsystem.
Old system:
65536 pages that map 256 bytes each
Mapping a new page overwrites old page
Granularity capped at 256 bytes minimum, requiring ST-001x to map
60:0000-00ff instead of 60:0000,0001
Classes inherit from MMIO and Memory, forcing only one mappable function
per class, and fixed names
MMIO sub-mapper inside memory: 00-3f:2000-5fff for one-byte granularity
Can dynamically change the map at run-time, MMC register settings
perform dynamic remapping
New system:
XML mapping is still based around banklo-bankhi:addrlo-addrhi, as that
shapes almost everything on the SNES very well
Internally, 2048 pages that map 8192 bytes each
Pages are vectors, scans O(n) from last to first (O(log n) would not
help, n is never > 3)
Can multi-cast writes, but not reads [for the obvious reason of: which
read do you return?]
Can map reads and writes separately
Granularity of one for entire 24-bit address range, no need for MMIO

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.

- 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 v095r05 release.
byuu says:
Changelog:
- GBA: lots of emulation improvements
- PPU PRAM is 16-bits wide
- DMA masks &~1/Half, &~3/Word
- VRAM OBJ 8-bit writes are ignored
- OAM 8-bit writes are ignored
- BGnCNT unused bits are writable*
- BG(0,1)CNT can't set the d13
- BLDALPHA is readable (fixes Donkey Kong Country, etc)
- SNES: lots of code cleanups
- sfc/chip => sfc/coprocessor
- UI: save most recent controller selection
GBA test scores: 1552/1552, 37/38, 1020/1260
(* forgot to add the value to the read function, so endrift's I/O tests
for them will fail. Fixed locally.)
Note: SNES is the only system with multiple controller/expansion port
options, and as such is the only one with a "None" option. Because it's
shared by the controller and expansion port, it ends up sorted first in
the list. This means that on your first run, you'll need to go to Super
Famicom->Controller Port 1 and select "Gamepad", otherwise input won't
work.
Also note that changing the expansion port device requires loading a new
cart. Unlike controllers, you aren't meant to hotplug expansion port
devices.

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.

byuu says:
You guys are going to hate the hell out of this one. It's twenty hours
of non-stop work, no exaggeration at all. Started at 4AM, just wrapped
up now at 8PM.
I rewrote the entire memory subsystem.
Old system:
65536 pages that map 256 bytes each
Mapping a new page overwrites old page
Granularity capped at 256 bytes minimum, requiring ST-001x to map
60:0000-00ff instead of 60:0000,0001
Classes inherit from MMIO and Memory, forcing only one mappable function
per class, and fixed names
MMIO sub-mapper inside memory: 00-3f:2000-5fff for one-byte granularity
Can dynamically change the map at run-time, MMC register settings
perform dynamic remapping
New system:
XML mapping is still based around banklo-bankhi:addrlo-addrhi, as that
shapes almost everything on the SNES very well
Internally, 2048 pages that map 8192 bytes each
Pages are vectors, scans O(n) from last to first (O(log n) would not
help, n is never > 3)
Can multi-cast writes, but not reads [for the obvious reason of: which
read do you return?]
Can map reads and writes separately
Granularity of one for entire 24-bit address range, no need for MMIO
- whatever is in XML is exactly what you get
Read/Write tables bind function callbacks, so I can have any number of
functions with any names from any classes with no inheritance (no
more uPD7725DR, uPD7725SR helpers, etc)
Less memory usage overall due to less tables [ I tried 16 million tables
and it used 2GB of RAM >_o ]
Cannot dynamically change the map at run-time, MMC read/write functions
perform address translation [worse average case speed, better worst
case speed]
Now the hate me part, functors can't beat virtual functions for speed.
There are speed penalties involved:
-4.5% on average games
-11% on SuperFX games (SFX has its own bus)
-15% on SA-1 games (SA-1 has two buses)
Of course the two that need the speed the most get the biggest hits.
I'm afraid there's really not a lot of wiggle room to boost speed back
up.
I suppose one bright spot is that we can much more easily try out
entirely new mapping systems now, since the dynamic portions have been
eliminated.

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:

thankfully with the new manifest-free folders, nobody will have to
do anything to use the new format. Just download the new version and

The Super Famicom Event stuff is currently broken (CC92/PF94
boards). That's gonna be fun to support.

Changelog:
- debugger compiles on all three profiles
- libsnes compiles on all three platforms (no API changes to libsnes)
- memory.cpp : namespace memory removed (wram -> cpu, apuram -> smp,
vram, oam, cgram -> ppu)
- sa1.cpp : namespace memory removed (SA-1 specific functions merged
inline to SA1::bus_read,write)
- GameBoy: added serial link support with interrupts and proper 8192hz
timing, but obviously it acts as if no other GB is connected to it
- GameBoy: added STAT OAM interrupt, and better STAT d1,d0 mode values
- UI: since Qt is dead, I've renamed the config files back to bsnes.cfg
and bsnes-geometry.cfg
- SA1: IRAM was not syncing to CPU on SA-1 side
- PPU/Accuracy and PPU/Performance needed Sprite oam renamed to Sprite
sprite; so that I could add uint8 oam[544]
- makes more sense anyway, OAM = object attribute memory, obj or
sprite are better names for Sprite rendering class
- more cleanup

You guys are going to hate the hell out of this one. It's twenty hours
of non-stop work, no exaggeration at all. Started at 4AM, just wrapped
up now at 8PM.
I rewrote the entire memory subsystem.
Old system:
65536 pages that map 256 bytes each
Mapping a new page overwrites old page
Granularity capped at 256 bytes minimum, requiring ST-001x to map
60:0000-00ff instead of 60:0000,0001
Classes inherit from MMIO and Memory, forcing only one mappable function
per class, and fixed names
MMIO sub-mapper inside memory: 00-3f:2000-5fff for one-byte granularity
Can dynamically change the map at run-time, MMC register settings
perform dynamic remapping
New system:
XML mapping is still based around banklo-bankhi:addrlo-addrhi, as that
shapes almost everything on the SNES very well
Internally, 2048 pages that map 8192 bytes each
Pages are vectors, scans O(n) from last to first (O(log n) would not
help, n is never > 3)
Can multi-cast writes, but not reads [for the obvious reason of: which
read do you return?]
Can map reads and writes separately
Granularity of one for entire 24-bit address range, no need for MMIO
- whatever is in XML is exactly what you get
Read/Write tables bind function callbacks, so I can have any number of
functions with any names from any classes with no inheritance (no
more uPD7725DR, uPD7725SR helpers, etc)
Less memory usage overall due to less tables [ I tried 16 million tables
and it used 2GB of RAM >_o ]
Cannot dynamically change the map at run-time, MMC read/write functions
perform address translation [worse average case speed, better worst
case speed]
Now the hate me part, functors can't beat virtual functions for speed.
There are speed penalties involved:
-4.5% on average games
-11% on SuperFX games (SFX has its own bus)
-15% on SA-1 games (SA-1 has two buses)
Of course the two that need the speed the most get the biggest hits.
I'm afraid there's really not a lot of wiggle room to boost speed back
up.
I suppose one bright spot is that we can much more easily try out
entirely new mapping systems now, since the dynamic portions have been
eliminated.

Changelog:
- debugger compiles on all three profiles
- libsnes compiles on all three platforms (no API changes to libsnes)
- memory.cpp : namespace memory removed (wram -> cpu, apuram -> smp,
vram, oam, cgram -> ppu)
- sa1.cpp : namespace memory removed (SA-1 specific functions merged
inline to SA1::bus_read,write)
- GameBoy: added serial link support with interrupts and proper 8192hz
timing, but obviously it acts as if no other GB is connected to it
- GameBoy: added STAT OAM interrupt, and better STAT d1,d0 mode values
- UI: since Qt is dead, I've renamed the config files back to bsnes.cfg
and bsnes-geometry.cfg
- SA1: IRAM was not syncing to CPU on SA-1 side
- PPU/Accuracy and PPU/Performance needed Sprite oam renamed to Sprite
sprite; so that I could add uint8 oam[544]
- makes more sense anyway, OAM = object attribute memory, obj or
sprite are better names for Sprite rendering class
- more cleanup
