Changelog:
- higan: target-tomoko has been renamed to target-higan
- Super Famicom: event has been renamed to
processor(architecture=uPD78214)
- Super Famicom: SNES-EVENT supported once more; under board IDs
EVENT-CC92 and EVENT-PF94
- Super Famicom: SNES-EVENT preliminarily set up to use DIP switch
settings ala the Nintendo Super System (incomplete)
- Super Famicom: MCC PSRAM moved inside the MCU, as it is remappable
- Super Famicom: MCC emulation rewritten from scratch; it is now
vastly more accurate than before
- Super Famicom: added BSC-1A5B9P-01 board definition to database;
corrected BS-MCC-RAM board definition
- Super Famicom: moved SHVC-LN3B-01 RAM outside of
processor(identifier=SDD1)
- higan: when selecting a default game to load for a new system entry,
it will change the system option to match the media type
- higan: the load text box on the system entry window is now editable;
can be used to erase entries
- icarus: fixed bug in Famicom importing
- icarus: importing unappended SNES coprocessor firmware will now
rename the firmware properly
- hiro/GTK,Qt: WM_CLASS is now set correctly in `argv[0]`, so
applications should show “higan”, “icarus” instead of “hiro” now
Note: if you wish to run the BS-X town cartridge, the database currently
lists the download RAM as type “PSRAM”. This needs to be changed to
“RAM” in order to load properly. Otherwise, the emulator will bomb
out on the load window, because BSC-1A5B9P-01 expects PSRAM to always be
present, but it won't find it with the wrong memory type. I'll correct
this in the database in a later release. For now, you can copy the game
portion of the manifest to a new manifest.bml file and drop it into the
gamepak folder until I fix the database.

Changelog:
- Super Famicom: fixed loading of BS Memory and Sufami Turbo
cartridges
- Super Famicom: renamed NSS to DIP; as that's really all it is, it's
not true NSS emulation
- Super Famicom: slot loading now happens inside of board parsing
instead of generically in loadCartridge()
- Super Famicom: BS-X cartridges with flash memory now serialize their
data and write it out to disk¹
- icarus: fixed Famicom game importing (hopefully) and set file import
title to “Load ROM File”
¹: there's no emulation of write commands yet, so the data is never
going to change anyway. This is just in preparation for more advanced
emulation of BS Memory cartridges.

Changelog:
- Super Famicom: everything outside of Nintendo Super System, Campus
Challenge '92 and Powerfest '94 should play
- Super Famicom: removed RAM from coprocessor/event (should use global
RAM)
- Super Famicom: removed RAM from SDD1 (should use global RAM)
- icarus: fixed Super Famicom game importing [hex_usr]
Also worth reminding that you'll need to disable database lookup in
order to run the BS-X Town cartridge right now. Plus, Star Ocean's
database entry still has the RAM in the wrong spot. The MSU1 code is not
looking at the right locations for data, so it's not going to work in
this release either.
I need to figure out what to call coprocessor/event and coprocessor/nss,
as neither are slots or processors like everything else.
Outside of those issues, all games for all systems should be playable,
at least to the extent they were in v106.
byuu says:
Changelog:
- major restructuring of board manifests
- cleanup of generic board names
- Super Famicom: updates to SA1, SuperFX, Cx4, SPC7110, EpsonRTC,
SharpRTC load/save code
- Super Famicom: added experimental SuperFX plot dithering fix
[qwertymodo]
- higan, icarus: rename shared folders to lowercase names; put .sys
folders into new subfolder
- Video Shaders/ → shaders/
- Database/ → database/
- Firmware/ → firmware/
- \*.sys/ → systems/\*.sys/
So right now, only standard SNES games, SA-1, SuperFX, and Cx4 games
load. I have not tested SPC7110 or RTC support, because icarus import
seems to be completely broken? It's creating blank folders when I try it
now. I'll have to fix that ...
Since we are now up to thirteen systems, I've put the .sys folders into
a subfolder. This should declutter the main higan-windows release folder
a good deal. Linux users will need to re-run make install, or manually
move things into a new systems/ subfolder.
Same goes for icarus: lowercase the database/ and firmware/ folders or
re-run make install.
I don't know if qwertymodo's SuperFX fix is exactly correct or not.
Hopefully it is, but I didn't write a test ROM or anything to be
certain. Since SuperFX games should run, if people could please play
through some of them and look for any regressions, that'd be very much
appreciated.

Changelog:
- tomoko: the library menu is now called the systems menu (even in
code)
- tomoko: added icons to menus (disambiguates systems menu entries)
- icarus: added missing .ws, .wsc extensions to scan dialog search
list
- higan: added Benesse - Pocket Challenge V2 emulation¹
¹: the Benesse - Pocket Challenge V2 is a WonderSwan (ASWAN) SoC
inside a custom designed shell. Games made for the WonderSwan (mostly)
run on the Pocket Challenge V2 and vice versa. The big difference is
that the Benesse has a different number of input buttons, that are also
named differently. Of course, right now, I don't know what the buttons
are named or where they're mapped on the 16-input keypad matrix I/O
port. It's also possible that the internal EEPROM doesn't exist, it
definitely has a unique (and also undumped) IPLROM, and other things.
The ROMs have their own .pc2 file extension. So it's getting its own
system entry.
What I'm going to do for v107 and above is utilize the new systems
configuration to mark the Benesse as hidden by default from the main
menu. I don't think anyone in the world will actually care or want to
play this, but there was really no reason not to add it.
byuu says:
Changelog:
- main menu renamed again (Library→System→Systems)
- the 'Hidden' checkbox on system properties was moved to the main
list as a 'Show' checkbox instead
- the move up/move down buttons on the systems panel now function
- added icons to indicate 'system' versus 'game boot' entries in the
systems list
I still didn't add ComboEdit to the Windows hiro port, so once again
this will be Linux/BSD only.
I polished the browse button for selecting a boot game. It'll use a list
of all bootable media file extensions, so that if you double-click any
supported game, it'll select it instead of going inside the folder. If
you pick a non-bootable folder, like say a Sufami Turbo cartridge, it
will go inside the folder instead, because it will treat it like any
other regular folder.
Having a checkbox next to text in the same cell doesn't work so well on
lists that have an onActivate action. Say you tried to double-click the
“Name” field on the Systems tab, it would toggle the checkbox twice
before popping open the system properties editor window. So because of
this, I made the show checkbox its own column. And for consistency, I
did the same for the slot# on the cheat editor window.
As a bit of really pedantic polish: if there are no systems enabled,
then the main menu won't show the separator before the “Load ROM Image”
option anymore.
I think something is wrong with the Markup::Node::insert syntax, but I
realized I have Markup::Node::swap, and just used that for the up/down
arrows on the systems panel for now. But we should probably fix insert()
at some point ... sigh.
byuu says:
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:
- game/memory/category → game/memory/content
- game/memory/model → game/memory/architecture
- game/memory/identity → game/memory/identifier
- Super Famicom: memory/content=Bitmap → memory/content=Save
- Super Famicom: memory/architecture=DMG,MGB →
memory/architecture=LR35902
The game manifest field names are now officially set in stone. I won't
change them again, I'll only add new fields if required.
As for the values in the field, I'm still undecided on the manufacturer
of the ST018, and I could be talked into different identifiers for the
Super Game Boy (SGB1/SGB2, DMG/MGB, or just ICD(2)?)
The board manifest format is still in flux, as is the choice of what to
name firmware files (it's between manufacturer and architecture, where
I'm leaning toward the latter currently.)
Board memory to Game memory mappings will require both the manufacturer
and architecture fields to match.
I'll be updating doc.byuu.org soon with the finalized game manifest
format.
byuu says:
Changelog:
- Emulator: update to final manifest syntax
- Super Famicom: new board syntax (still experimental)
- Super Famicom: match (manufacturer.)category.type instead of
(model.)category.type
Errata:
- Markup::Node::find() needs to be extended to support multiple
subtype matches
- Sufami Turbo ROM/RAM nodes are part of separate gamepaks; need to
refactor this
byuu says:
Changelog:
- manifest: memory/battery now resides under type at
memory/type/battery
- genius: volatile option changed to battery; auto-disables when not
RAM or RTC type
- higan: added new Emulator::Game class to parse manifests for all
emulated systems consistently
- Super Famicom: board manifest appended to manifest viewer now
- Super Famicom: cartridge class updated to use Emulator::Game objects
- hiro: improve suppression of userland callbacks once
Application::quit() is called
- this fixes a crash in genius when closing the window with a tree
view item selected
My intention is to remove Emulator::Interface::sha256(), as it's not
really useful. They'll be removed from save states as well. I never
bothered validating the SHA256 within them, because that'd be really
annoying for ROM hackers.
I also intend to rename Emulator::Interface::title() to label() instead.
Most everything is still broken. The SNES still needs all the board
definitions updated, all the other cores need to move to using
Emulator::Game.
byuu says:
Changelog:
- higan, icarus, genius: new manifest syntax (work in progress)
Pretty much only LoROM and HiROM SNES games will load right now, and RAM
will only work right if the save.ram file already exists to pull its
file size from (a temporary cheap hack was used.)
Basically, I'm just getting this out there for evaluation.
One minor errata is that I switched icarus to using “memory/battery” to
indicate battery-backed RAM, whereas genius still uses “memory/volatile”
to indicate non-battery-backed RAM.
I intend to make it “memory/battery” in genius, and have the field
auto-enable when RAM or RTC is selected for type (obviously allowing it
to be unchecked for volatile memory.)
I need to update all 64 production boards, and 25 of 29 generic boards,
to use the new slot syntax; and I also need to update every single core
in higan to use the new manifest game syntax. I want to build out a
generic manifest game parser that all emulation cores will use.
Once I finish this, I'll also need to write a database converter to
update all of my licensed game dumps to the new database syntax.
I also need to write up something for doc.byuu.org explaining the new
manifest game syntax. The manifest board syntax will still be “internal”
and subject to revisions, but once v107 is out, the gamepak manifest
format will be set in stone sans extensions.
byuu says:
Changelog:
- Game Boy: fixed RAM/RTC saving¹
- Super Famicom: ICD2 renamed to ICD (there exists an SGB prototype
with a functionally identical ICD1)
- Sufami Turbo: removed short-circuiting when loading an unlinkable
cartridge into slot A²
- Super Game Boy: the 20971520hz clock of the SGB2 is now emulated
- Super Famicom: BSC-1Lxx (SA1) boards now prompt for BS memory
cartridges; and can make use of them³
- Super Famicom: fixed a potential for out-of-bounds reads with BS
Memory flash carts
¹: I'm using a gross hack of replacing `type: ` with `type:` so that
`memory(type=...)` will match without the extra spaces. I need to
think about whether I want the BPath query syntax to strip whitespace or
not. But longer term, I want to finalize game/memory's design, and build
a higan/emulation/manifest parser that produces a nicer interface to
reading manifests for all cores, which will make this irrelevant for
higan anyway.
²: I don't think it's appropriate for higan to enforce this. Nothing
stops you from inserting games that can't be linked into a real Sufami
Turbo. I do short-circuit if you cancel the first load, but I may allow
loading an empty slot A with a populated slot B. I think the BIOS does
something when you do that. Probably just yells at you.
³: I know it's emulated correctly now, but I still don't know what
the heck changes when you load the SD Gundam G Next - Unit & Map
Collection BS Memory cartridge with SD Gundam G Next to actually test
it.
byuu says:
Changelog:
- Super Game Boy: for the 50th time, higan won't segfault if you
cancel the Game Boy cartridge load request
- icarus: moved to new manifest syntax for all remaining systems
- Game Boy: moved to new manifest syntax
Errata:
- Game Boy: save RAM does not appear to be working for some reason
- Famicom: higan won't even start to run this system; it just acts
like a cartridge was never loaded ...
- cores outside of the Super Famicom and Game Boy/Color will not run
due to icarus/higan manifest syntax differences

Changelog:
- icarus: new Firmware/ folder, which is used to import external
firmware when it's missing from the ROM image
- icarus: improved Super Famicom heuristics; including Shift-JIS to

- if firmware isn't appended, it still cuts out the size from the
memory/program.rom file
- boards.bml is still missing the new Japanese production boards
byuu says:
Changelog:
- Super Famicom: added remaining generic board types
- icarus: improved Super Famicom heuristics
- icarus: reworked BS Memory heuristics
- icarus: reworked Sufami Turbo heuristics
Notes: this is really complicated, and is going to take a long time to
work 100% smoothly again.
Starting off, I am trying to get rid of the weird edge case zero-byte
SRAM mapping for the Cx4. It has the RAM region present, but returns
logic low (0x00) instead of open bus, when SRAM isn't present. I started
by making it `map=ram` instead of `ram/map`, which is gross, and then it ended
up detecing the map tag ending in RAM and pulling the Cx4 data RAM into that
slot. Ugh. The preservation board mapping is still as it was before and will
need to be updated once I get the syntax down.
The BS Memory and Sufami Turbo moving to the new `game/memory`
ending means I can't use the SuperFamicom::Cartridge::loadMemory
function that looks at the old-style rom/ram tags. Because I didn't
write more code, the result is those sub-carts won't load now.
The old heuristics were short-circuiting on SA1 before bothering with
BS-X slots, so that's why SD Gundam G-Next wasn't asking for a data
pack. The problem is, I don't know where the BS-X pack maps to on this
cartridge. It's at c0-ef on the other BS-X slotted cartridges, but
that's mapped to the SA1 on regular SA1 cartridges, so ... for now, it's
not actually mapped in.
I'm still struggling with naming conventions on all these boards. I'll
make a public post about that, though.
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:
- Super Famicom: update to newer board markup syntax
- Super Famicom: update all mapped ROMs to be write-protected
- errata: SPC7110 set ram.writeProtect(true), I'll fix it in the
next WIP
- icarus: rewrote the Super Famicom heuristics module from scratch
Instead of icarus heuristics generating higan-specific mappings, it now
generates generic board IDs that can be used by any emulator. I had
originally planned to print out real PCB ID codes here, but these board
mappings are meant to be more generic, and I don't want them to look
real. The pseudo-codes are easy to parse, for example: `DSP-LOROM-NVRAM`
for Super Mario Kart, `SUPERFX-RAM` for Doom.
I'm going to make a `Boards (Generic).bml` file that will contain mapping
definitions for every board. Until this is done, any games not in the SNES
preservation database will fail to play because the mapping information is
now missing.
byuu says:
Changelog:
- Super Famicom: added support for loading manifests without embedded
mapping information¹
- genius: initial commit
- various Makefile cleanups
¹: so the idea here is to try and aim for a stable manifest format,
and to allow direct transposition of icarus/genius database entries into
manifest files. The exact mechanics of how this is going to work is
currently in flux, but we'll get there.
For right now, `Super Famicom.sys` gains `boards.bml`, which is the raw
database from my board-editor tool, and higan itself tries to load
`boards.bml`, match an entry to game/board from the game's `manifest.bml`
file, and then transform it into the format currently used by higan. It
does this only when the game's `manifest.bml` file lacks a board node.
When such a board node exists, it works as previous versions of higan
did.
The only incompatible change right now is information/title is now
located at game/label. I may transition window title display to just use
the filenames instead.
Longer term, some thought is going to need to go into the format of the
`boards.bml` database itself, and at which point in the process I should
be transforming things.
Give it time, we'll refine this into something nicer.

- icarus: more PAL games added to the SNES database
I hope I've implemented R correctly. It should only increment twice on
DD,FD CB xx instructions. LDI/LDD/LDIR/LDDR should work as expected as
well. It increments once when interrupts are executed (and not maksed.)
The top bit is ignored in increments.
byuu says:
Changelog (since v105tr1):
Changelog:
- added Emulation/AutoSaveMemory/Interval setting to specify number of
seconds between auto-saves
- added Game Notes tool
- added 64 new SNES PAL games to the icarus preservation database
The Games Notes tool is a new feature that gives you a blank text box to
enter notes about a game that you're playing: so you can write down
things like level select codes for games with save RAM, combo moves, or
whatever other information you'd like quick and easy access to.
This is kind of an experiment. Ideally, we'd wanna allow more
personalized information, drawings, etc. But hey, let's try it out and
see what people think.
It seems on Windows, `compiler` has defaulted to `g++` for a while now,
so we didn't need to override it in the `make` invocation.
Since v105r01, `compiler` defaults to `g++` on Linux too, so we don't
need to override it there either.
By default, mkdocs uses "highlight.js" to apply syntax-highlighting
to code blocks. Left to its own devices, highlight.js will guess the
language being used in the code block, apply the "hljs" CSS class
(so the code block will be given a nice border, a sensible font-size,
etc.) and apply the appropriate formatting markup. If it guesses wrongly,
you can give a language hint on the opening line of the block.
If you use a language that highlight.js does not recognise, or
the special name "nohighlight", highlight.js will leave the block
alone. Unfortunately, in mkdocs' default theme, that means it will be
formatted like *inline* code, with a border and background that wraps
behind each line of the block.
In order to make a code-block that looks like a code-block, you have
to carefully pick a language that highlight.js has heard of, but whose
syntax is sufficiently different from whatever's in the block that no
unwanted highlighting will occur.
This seems to be fixed in the readthedocs theme that comes with mkdocs
0.16.1, but ReadTheDocs doesn't actually seem to be using that version. :/

continues to be GPL version 3 only (no "or later" clause).
Loading and unloading the RTC is a little odd, since it's normally
always powered in the first place. What we want, and what the load()
functions really do, is to resync using the saved timestamps or
reset it. unload() proper doesn't do anything.
However, an interface refactoring after v098 reordered the above
operations, and this (along with a typo, shh!) was causing the already
synced time to be cleared.
I've added checks so that whenever rtc.ram can't be found, load() gets
called with empty arguments to initialise the defaults (like putting
in a fresh battery).
git requires a name and email to be configured before it can commit a change. We're not going to push the merge result anywhere, so we don't strictly speaking need it to commit.
