Changelog:
- Super Game Boy: fixed loading of boot ROM
- hiro: added ComboEdit::setEditable(bool = true);
- tomoko: added new systems settings panel
Note!!: this release will not compile on Windows or macOS due to the
missing ComboEdit control! I'll try to merge in hex's implementation
for the Windows release here soon. macOS users will probably be out of
luck for a while, sorry.
The new systems panel is an idea I've been meaning to implement for
quite a while, but finally got around to starting on it. It's still
fairly unpolished, but the basic idea is there for Linux/BSD users to
try out now.
So imagine the Super Game Boy, BS-X Satellaview, Sufami Turbo, and the
associated BS Memory Pack-slotted SNES cartridges. To play any of those,
you needed to choose Nintendo→Super Famicom, and then select the
relevant cartridge, and then select any slotted cartridges to play with
it.
This was acceptable-ish, if not ideal. But now imagine in the future if
we wanted to support the Famicom Disk System, which is technically a
cartridge that plugs into the Famicom deck. Or the PC Engine CD, which
has one of three special HuCards that must be inserted (ignoring the
Turbo Duo where it's built-in—I'm going to be emulating the Super CD
as if you're using a stock PCE CD.) Or the Mega CD, where there are
probably a half dozen or more BIOS + hardware revisions that are
region-specific, which connect to an expansion port that is identical to
the cartridge port save for the Mega Drive seeing an I/O register bit
toggled here.
In all of these cases, it's going to be a real pain to have to choose
the 'BIOS' every time you want to play a game for them.
I can't distribute these BIOSes with higan due to copyright
restrictions, and trying to ship dummy folders for every possible
combination would become quite odious, and difficult for people to use
(compare to setting up the Game Boy Advance system BIOS.)
And so I've created the new systems settings panel. Here, you can manage
a list of systems that show up under the higan library menu (now renamed
to “System”), where each entry contains name, boot, and hidden
parameters.
The name parameter is what shows up in the system menu. You can call any
system higan emulates whatever you like here. Don't like “Super
Famicom”? Change it to “SNES”, then.
The boot parameter is a combo edit with a dropdown for all of the
systems higan emulates. If you choose one of these, then the higan
system menu option will work exactly like in previous releases, and
prompt you for a cartridge. But if you choose the browse button next to
the combo edit control, you'll get to pick any gamepak from the higan
library of your choosing.
So you could choose the SGB2 BIOS, and name the menu option “Super Game
Boy 2”, and when you choose the menu option, it will load the SFC core,
load the SGB2 BIOS, and only prompt you for the Game Boy game you wish
to play on it. The same deal goes for the FDS, PCE-CD, Mega CD, Mega
Drive Sonic & Knuckles lock-on cartridge, BS-X Satellaview, SD Gundam
G-Next, etc. Whatever you want to be in the menu, you can put in there
by pointing higan at the appropriate 'BIOS' gamepak to load.
Astute readers have probably already noticed, but you can technically
use this on non-slotted games as well, thus creating instant boot
options for your absolute favorite games, if you so wanted. Point it at
Zelda 3, and you can boot it instantly from the main menu, without any
need for file selection.
The hidden option is a way to hide the system entries from the system
menu. Primarily this would be a fast way for users to disable emulation
cores they never use in higan, without having to remove the options.
The major concession with this change is the collapsing of the
per-manufacturer submenus. What this means is you will now have all
twelve higan emulated systems in the main menu by default. This makes
the list rather long, but ... oh well. I may try to offer some form of
grouping in the future, but the grouping defeats the “list order =
display order” design, and I'm not willing to auto-sort the list. I want
people to be able to control the ordering of the system menu, and have
added (as yet non-functional) sorting arrows for that purpose. I also
don't have a combined tree+table view widget in higan to try to and
group things. But ... we'll see how things go in the future.
Another idea is to add a specialty load option that opens up the user's
Emulation library path, and lets you pick a gamepak for any system,
which would boot the same way as when you drop a gamepak onto the higan
executable or main window. So say you almost never play Wonderswan
games, this would be a way to play them without them cluttering your
system menu list.
The “import ROM files” option has been removed. All it does is launch
icarus directly. I would rather users become familiar with using icarus.
The “load ROM file” option remains.
Anyway, this is all still a work in progress, so please give it time and
don't overload me with too many suggested changes right now, thanks :3

Changelog:
- game/memory/type/battery → game/memory/volatile
- (manufacturer.)content.type → (architecture.)content.type
- nall: Markup::find() strips spaces from values in comparisons
- higan: updated game manifest loading/saving code for all cores
- GBA: flash memory ID is internally selected based on the
manufacturer and memory size
- SFC: ST018 (ARM6) frequency can be modified via game manifest now
- WS: EEPROM::name removed (not useful)
- icarus, genius: battery→volatile updates
I did my best to look over the diff between r13 and r14, but it's 84KiB
excluding the game database changes. It's just too much for me. I'd
greatly appreciate if someone could look over it and check for any
errors in this update. But more than likely, I suppose we'll iron out
any issues by determining which games fail to load.
Right now, I know the Super Game Boy support doesn't seem to work. But
all non-SFC cores should work fully, and all normal + NEC DSP SFC games
should work as well. Unsure about the rest.
Also, I'm planning to change the Game Boy “MBC1M” mapper to “MBC1#A” to
indicate it's an alternate wiring configuration of the stock MBC1, and
not a new mapper type.
byuu says:
Changelog:
- nall: `Markup::Node::operator[]` now uses `find()` instead of `lookup()`
behind the scenes
- Super Famicom: RAM memory ordering is now independent of ROM memory
ordering
- Super Famicom: added 19 new generic board definitions
- icarus: improved Super Famicom heuristics generation
Not putting it in the changelog, but the SPC7110 RAM now has write
protection disabled again.
99% of games should now be playable with heuristics. The exceptions
should be:
- 4MB LoROM games with SRAM (Ys 3, FE: Thracia 776)
- 2MB DSP LoROM games
- BS-X Town
- BS-X slotted games
- SA1 BSX slotted games
- SPC7110 games without the RTC (Momotarou Dentetsu Happy, Super Power
League 4)
- SPC7110 7MB fan translation (wasn't supported earlier either)
- ExLoROM games (wasn't supported earlier either)
- Sufami Turbo
- Campus Challenge '92 and Powerfest '94
- ST010 is going to run at 15MHz instead of 11MHz
- MSU1 (needs to be supported in higan, not icarus)
I'll add support for most of these before the release of v107.
byuu says:
Changelog:
- added 30 new PAL games to icarus (courtesy of Mikerochip)
- new version of libco no longer requires mprotect nor W|X permissions
- nall: default C compiler to -std=c11 instead of -std=c99
- nall: use `-fno-strict-aliasing` during compilation
- updated nall/certificates (hopefully for the last time)
- updated nall/http to newer coding conventions
- nall: improve handling of range() function
I didn't really work on higan at all, this is mostly just a release
because lots of other things have changed.
The most interesting is `-fno-strict-aliasing` ... basically, it joins
`-fwrapv` as being "stop the GCC developers from doing *really* evil
shit that could lead to security vulnerabilities or instabilities."
For the most part, it's a ~2% speed penalty for higan. Except for the
Sega Genesis, where it's a ~10% speedup. I have no idea how that's
possible, but clearly something's going very wrong with strict aliasing
on the Genesis core.
So ... it is what it is. If you need the performance for the non-Genesis
cores, you can turn it off in your builds. But I'm getting quite sick of
C++'s "surprises" and clever compiler developers, so I'm keeping it on
in all of my software going forward.
byuu says:
Changelog:
- Emulator: use `(uintmax)-1 >> 1` for the units of time
- MD: implemented 13 new 68K instructions (basically all of the
remaining easy ones); 21 remain
- nall: replaced `(u)intmax_t` (64-bit) with *actual* `(u)intmax` type
(128-bit where available)
- this extends to everything: atoi, string, etc. You can even
print 128-bit variables if you like
22,552 opcodes still don't exist in the 68K map. Looking like quite a
few entries will be blank once I finish.
byuu says:
Changelog:
- nall::lstring -> nall::string_vector
- added IntegerBitField<type, lo, hi> -- hopefully it works correctly...
- Multitap 1-4 -> Super Multitap 2-5
- fixed SFC PPU CGRAM read regression
- huge amounts of SFC PPU IO register cleanups -- .bits really is lovely
- re-added the read/write(VRAM,OAM,CGRAM) helpers for the SFC PPU
- but they're now optimized to the realities of the PPU (16-bit data
sizes / no address parameter / where appropriate)
- basically used to get the active-display overrides in a unified place;
but also reduces duplicate code in (read,write)IO
byuu says:
Changelog:
- (u)int(max,ptr) abbreviations removed; use _t suffix now [didn't feel
like they were contributing enough to be worth it]
- cleaned up nall::integer,natural,real functionality
- toInteger, toNatural, toReal for parsing strings to numbers
- fromInteger, fromNatural, fromReal for creating strings from numbers
- (string,Markup::Node,SQL-based-classes)::(integer,natural,real)
left unchanged
- template<typename T> numeral(T value, long padding, char padchar)
-> string for print() formatting
- deduces integer,natural,real based on T ... cast the value if you
want to override
- there still exists binary,octal,hex,pointer for explicit print()
formatting
- lstring -> string_vector [but using lstring = string_vector; is
declared]
- would be nice to remove the using lstring eventually ... but that'd
probably require 10,000 lines of changes >_>
- format -> string_format [no using here; format was too ambiguous]
- using integer = Integer<sizeof(int)*8>; and using natural =
Natural<sizeof(uint)*8>; declared
- for consistency with boolean. These three are meant for creating
zero-initialized values implicitly (various uses)
- R65816::io() -> idle() and SPC700::io() -> idle() [more clear; frees
up struct IO {} io; naming]
- SFC CPU, PPU, SMP use struct IO {} io; over struct (Status,Registers) {}
(status,registers); now
- still some CPU::Status status values ... they didn't really fit into
IO functionality ... will have to think about this more
- SFC CPU, PPU, SMP now use step() exclusively instead of addClocks()
calling into step()
- SFC CPU joypad1_bits, joypad2_bits were unused; killed them
- SFC PPU CGRAM moved into PPU::Screen; since nothing else uses it
- SFC PPU OAM moved into PPU::Object; since nothing else uses it
- the raw uint8[544] array is gone. OAM::read() constructs values from
the OAM::Object[512] table now
- this avoids having to determine how we want to sub-divide the two
OAM memory sections
- this also eliminates the OAM::synchronize() functionality
- probably more I'm forgetting
The FPS fluctuations are driving me insane. This WIP went from 128fps to
137fps. Settled on 133.5fps for the final build. But nothing I changed
should have affected performance at all. This level of fluctuation makes
it damn near impossible to know whether I'm speeding things up or slowing
things down with changes.
byuu says:
Changelog:
- nall/vector rewritten from scratch
- higan/audio uses nall/vector instead of raw pointers
- higan/sfc/coprocessor/sdd1 updated with new research information
- ruby/video/glx and ruby/video/glx2: fuck salt glXSwapIntervalEXT!
The big change here is definitely nall/vector. The Windows, OS X and Qt
ports won't compile until you change some first/last strings to
left/right, but GTK will compile.
I'd be really grateful if anyone could stress-test nall/vector. Pretty
much everything I do relies on this class. If we introduce a bug, the
worst case scenario is my entire SFC game dump database gets corrupted,
or the byuu.org server gets compromised. So it's really critical that we
test the hell out of this right now.
The S-DD1 changes mean you need to update your installation of icarus
again. Also, even though the Lunar FMV never really worked on the
accuracy core anyway (it didn't initialize the PPU properly), it really
won't work now that we emulate the hard-limit of 16MiB for S-DD1 games.
byuu says:
New update. Most of the work today went into eliminating hiro::Image
from all objects in all ports, replacing with nall::image. That took an
eternity.
Changelog:
- fixed crashing bug when loading games [thanks endrift!!]
- toggling "show status bar" option adjusts window geometry (not
supposed to recenter the window, though)
- button sizes improved; icon-only button icons no longer being cut off
byuu says:
Changelog:
- entire GBA core ported to auto function() -> return; syntax
- fixed GBA BLDY bug that was causing flickering in a few games
- replaced nall/config usage with nall/string/markup/node
- this merges all configuration files to a unified settings.bml file
- added "Ignore Manifests" option to the advanced setting tab
- this lets you keep a manifest.bml for an older version of higan; if
you want to do regression testing
Be sure to remap your controller/hotkey inputs, and for SNES, choose
"Gamepad" from "Controller Port 1" in the system menu. Otherwise you
won't get any input. No need to blow away your old config files, unless
you want to.
byuu says:
Changelog:
- fixed I/O register reads; perfect score on endrift's I/O tests now
- fixed mouse capture clipping on Windows [Cydrak]
- several hours of code maintenance work done on the SFC core
All higan/sfc files should now use the auto fn() -> ret; syntax. Haven't
converted all unsigned->uint yet. Also, probably won't do sfc/alt as
that's mostly just speed hack stuff.
Errata:
- forgot auto& instead of just auto on SuperFamicom::Video::draw_cursor,
which makes Super Scope / Justifier crash. Will be fixed in the next
WIP.
byuu says:
Note: you will need the new icarus (and please use the "no manifest"
system) to run GBA games with this WIP.
Changelog:
- fixed caching of r(d) to pass armwrestler tests [Jonas Quinn]
- DMA to/from GBA BIOS should fail [Cydrak]
- fixed sign-extend and rotate on ldrs instructions [Cydrak]
- fixed 8-bit SRAM reading/writing [byuu]
- refactored GBA/cartridge
- cartridge/rom,ram.type is now cartridge/mrom,sram,eeprom,flash
- things won't crash horribly if you specify a RAM size larger than
the largest legal size in the manifest
- specialized MROM / SRAM classes replace all the shared read/write
functions that didn't work right anyway
- there's a new ruby/video.glx2 driver, which is not enabled by default
- use this if you are running Linux/BSD, but don't have OpenGL 3.2 yet
- I'm not going to support OpenGL2 on Windows/OS X, because these OSes
don't ship ancient video card drivers
- probably more. What am I, clairvoyant? :P
For endrift's tests, this gets us to 1348/1552 memory and 1016/1260
timing. Overall, this puts us back in second place. Only no$ is ahead
on memory, but bgba is even more ahead on timing.
byuu says:
Changelog:
- return open bus instead of mirroring addresses on the bus (fixes
Mario&Luigi, Minish Cap, etc) [Jonas Quinn]
- add boolean flag to load requests for slotted game carts (fixes slot
load prompts)
- rename BS-X Town cart from psram to ram
- icarus: add support for game database
Note: I didn't rename "bsx" to "mcc" in the database for icarus before
uploading that. But I just fixed it locally, so it'll be in the next
WIP. For now, make it create the manifest for you and then rename it
yourself. I did fix the PSRAM size to 256kbit.
byuu says:
I'll post more detailed changes later, but basically:
- fixed Baldur's Gate bug
- guess if no flash ROM ID present (fixes Magical Vacation, many many
others)
- nall cleanups
- sfc/cartridge major cleanups
- bsxcartridge/"bsx" renamed to mcc/"mcc" after the logic chip it uses
(consistency with SGB/ICD2)
- ... and more!
byuu says:
Changelog:
- synchronizes lots of nall changes
- changes displayed program title from tomoko to higan(*)
- browser dialog sort is case-insensitive
- .sys folders look at user-selected library path; no longer hard-coded
Tried to get rid of the file modes from the Windows browser dialog, but
it was being a bitch so I left it on for now.
- The storage locations and binary still use tomoko. I'm not really sure
what to do here. The idea is there may be more than one "higan" UI in
the future, but I don't want people to go around calling the entire
program by the UI name. For official Windows releases, I can rename
the binaries to "higan-{profile}.exe", and by putting the config files
with the binary, they won't ever see the tomoko folder. Linux is of
course trickier.
Note: Windows users will need to edit hiro/components.hpp and comment
out these lines:
#define Hiro_Console
#define Hiro_IconView
#define Hiro_SourceView
#define Hiro_TreeView
I forgot to do that, and too lazy to upload another WIP.
byuu says:
Main reason for this WIP was because of all the added lines to hiro for
selective component disabling. May as well get all the diff-noise apart
from code changes.
It also merges something I've been talking to Cydrak about ... making
nall::string::(integer,decimal) do built-in binary,octal,hex decoding
instead of just failing on those. This will have fun little side effects
all over the place, like being able to view a topic on my forum via
"forum.byuu.org/topic/0b10010110", heh.
There are two small changes to higan itself, though. First up, I fixed
the resampler ratio when loading non-SNES games. Tested and I can play
Game Boy games fine now. Second, I hooked up menu option hiding for
reset and controller selection. Right now, this works like higan v094,
but I'm thinking I might want to show the "Device -> Controller" even if
that's all that's there. It kind of jives nicer with the input settings
window to see the labels there, I think. And if we ever do add more
stuff, it'll be nice that people already always expect that menu there.
Remaining issues:
* add slotted cart loader (SGB, BSX, ST)
* add DIP switch selection window (NSS)
* add timing configuration (video/audio sync)
byuu says:
Okay yeah, lots of SNES coprocessor games were horribly broken. They
should be fixed now with the below changes:
Old syntax:
auto programROM = root["rom[0]/name"].text();
auto dataROM = root["rom[1]/name"].text();
load_memory(root["ram[0]"]);
New syntax:
auto rom = root.find("rom");
auto ram = root.find("ram");
auto programROM = rom(0)["name"].text();
auto dataROM = rom(1)["name"].text();
load_memory(ram(0));
Since I'm now relying on the XShm driver, which is multi-threaded, I'm
now compiling higan with -fopenmp. On FreeBSD, this requires linking
with -Wl,-rpath=/usr/local/lib -Wl,-rpath=/usr/local/lib/gcc49 to get
the right version of GOMP.
This gives a pretty nice speed boost for XShm, I go from around 101fps
to 111fps at 4x scale on the accuracy profile. The combination of
inlining the accuracy-PPU and parallelizing the XShm renderer about
evenly compensates now for the ~20% CPU overclock I gave up a while ago.
The WIP also has some other niceties from the newer version of nall.
Most noticeably, cheat code database searching is now instantaneous. No
more 3-second stall.
byuu says:
This updates higan to use the new Markup::Node changes. This is a really
big change, and one slight typo anywhere could break certain classes of
games from playing.
I don't have ananke hooked up again yet, so I don't have the ability to
test this much. If anyone with some v094 game folders wouldn't mind
testing, I'd help out a great deal.
I'm most concerned about testing one of each SNES special chip game.
Most notably, systems like the SA-1, HitachiDSP and NEC-DSP were using
the fancier lookups, eg node["rom[0]/name"], which I had to convert to
a rather ugly node["rom"].at(0)["name"], which I'm fairly confident
won't work. I'm going to blame that on the fumes from the shelves I just
stained >.> Might work with node.find("rom[0]/name")(0) though ...? But
so ugly ... ugh.
That aside, this WIP adds the accuracy-PPU inlining, so the accuracy
profile should run around 7.5% faster than before.
byuu says:
This will easily be the biggest diff in the history of higan. And not in
a good way.
* target-higan and target-loki have been blown away completely
* nall and ruby massively updated
* phoenix replaced with hiro (pretty near a total rewrite)
* target-higan restarted using hiro (just a window for now)
* all emulation cores updated to compile again
* installation changed to not require root privileges (installs locally)
For the foreseeable future (maybe even permanently?), the new higan UI
will only build under Linux/BSD with GTK+ 2.20+. Probably the most
likely route for Windows/OS X will be to try and figure out how to build
hiro/GTK on those platforms, as awful as that would be. The other
alternative would be to produce new UIs for those platforms ... which
would actually be a good opportunity to make something much more user
friendly.
Being that I just started on this a few hours ago, that means that for
at least a few weeks, don't expect to be able to actually play any
games. Right now, you can pretty much just compile the binary and that's
it. It's quite possible that some nall changes didn't produce
compilation errors, but will produce runtime errors. So until the UI can
actually load games, we won't know if anything is broken. But we should
mostly be okay. It was mostly just trim<1> -> trim changes, moving to
Hash::SHA256 (much cleaner), and patching some reckless memory copy
functions enough to compile.
Progress isn't going to be like it was before: I'm now dividing my time
much thinner between studying and other hobbies.
My aim this time is not to produce a binary for everyone to play games
on. Rather, it's to keep the emulator alive. I want to be able to apply
critical patches again. And I would also like the base of the emulator
to live on, for use in other emulator frontends that utilize higan.
byuu says:
Changelog:
- nall: fixed major memory leak in string class
- ruby: video shaders support #define-based settings now
- phoenix/GTK+: support > 256x256 icons for window / task bar / alt-tab
- sfc: remove random/ and config/, merge into system/
- ethos: delete higan.png (48x48), replace with higan512.png (512x512)
as new higan.png
- ethos: default gamma to 100% (no color adjustment)
- ethos: use "Video Shaders/Display Emulation/" instead of "Video
Shaders/Emulation/"
- use g++ instead of g++-4.7 (g++ -v must be >= 4.7)
- use -std=c++11 instead of -std=gnu++11
- applied a few patches from Debian upstream to make their packaging job
easier
So because colors are normalized in GLSL, I won't be able to offer video
shaders absolute color literals. We will have to perform basic color
conversion inside the core.
As such, the current plan is to create some sort of Emulator::Settings
interface. With that, I'll connect an option for color correction, which
will be on by default. For FC/SFC, that will mean gamma correction
(darker / stronger colors), and for GB/GBC/GBA, it will mean simulating
the weird brightness levels of the displays. I am undecided on whether
to use pea soup green for the GB or not. By not doing so, it'll be
easier for the display emulation shader to do it.
byuu says:
Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)
- audio buffer clears when entering a modal loop on Windows (prevents
audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.
