- nall/GNUmakefile: fixed findstring parameter arguments [Screwtape]
- nall/Windows: always include -mthreads -lpthread for all
applications
- nall/memory: code restructuring
I really wanted to work on the new PPU today, but I thought I'd spend a
few minutes making some minor improvements to nall::memory, that was
five and a half hours ago. Now I have a 67KiB diff of changes. Sigh.

Changelog:
- SNES: started on skeleton of the new parallel PPU core
To build the new PPU core, set profile=fast via GNU make. The old core
is profile=accurate.
The names of the profiles, and the name of the folder for the fast PPU
are subject to change.
The new PPU core doesn't do anything but demonstrate the proof of
concept: every scanline, make a copy of all the PPU registers and CGRAM.
Share the VRAM and OAM. Batch render all scanlines at once using OpenMP
at the end of each frame and blit the result.
With no PPU core at all, bsnes runs 91% faster than with the accuracy
PPU (230fps vs 120fps.) That's the absolute theoretical best-case
scenario. With the skeleton in place, we're already around 220fps. It'll
go down more as the PPU line renderer starts to do real work. I don't
know where things will end up yet. I suppose we'll find out in time.
My own copy of TDM/GCC can't use OpenMP on Windows, so ... it won't
parallelize if you build with that. I'm going to have to switch to a
different MinGW distribution once this is complete, I suppose.

Changelog:
- nall: merged Path::config() and Path::local() to Path::userData()
- ~/.local/share or %appdata or ~/Library/ApplicationSupport
- higan, bsnes: render main window icon onto viewport instead of
canvas
- should hopefully fix a brief flickering glitch that appears on
Windows
- icarus: improved Super Famicom heuristics for Starfox / Starwing RAM
- ruby/Direct3D: handle viewport size changes in lock() instead of
output()
- fixes icon disappearing when resizing main window
- hiro/Windows: remove WS_DISABLED from StatusBar to fix window
resize grip
- this is experimental: I initially used WS_DISABLED to work
around a focus bug
- yet trying things now, said bug seems(?) to have gone away at
some point ...
- bsnes: added advanced settings panel with real-time driver change
support
I'd like feedback on the real-time driver change, for possible
consideration into adding this to higan as well.
Some drivers just crash, it's a fact of life. The ASIO driver in
particular likes to crash inside the driver itself, without any error
messages ever returned to try and catch.
When you try to change a driver with a game loaded, it gives you a scary
warning, asking if you want to proceed.
When you change a driver, it sets a crash flag, and if the driver
crashes while initializing, then restarting bsnes will disable the
errant driver. If it fails in a recoverable way, then it sets the driver
to “None” and warns you that the driver cannot be used.
What I'm thinking of further adding is to call emulator→save() to
write out the save RAM contents beforehand (although the periodic
auto-saving RAM will handle this anyway when it's enabled), and possibly
it might be wise to capture an emulator save state, although those can't
be taken without advancing the emulator to the next frame, so that might
not be a good idea.
I'm also thinking we should show some kind of message somewhere when a
driver is set to “None”. The status bar can be hidden, so perhaps on the
title bar? Or maybe just a warning on startup that a driver is set to
“None”.

Yeah, you read right: recent games menu, path settings. And dynamic rate
control + screensaver suppression is on the todo list. I'm not fucking
around this time. I really want to make something special here.

Changelog:
* yes.
But seriously, a list of changes on a pre-alpha GUI is going to get annoying.
Basically, work on embedding stuff in the binary, firmware loading (both
appended to the ROM and in a firmware/ subfolder) added, SGB games can be
loaded, config file holds more values for driver settings, added ruby drivers to
other platforms, etc.
byuu says:
Changelog:
- bsnes: work on the new GUI; can load games now, but no input support
yet
- icarus: heuristics game/label uses filename instead of internal
header name
byuu says:
Changelog:
- created new bsnes target (it currently does nothing)
- Super Famicom: fixed BS Memory pack support in the MCC emulation
- icarus: fixed manifest-free support for BS Memory flash-based
cartridges
- icarus: database improvements
byuu says:
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.
byuu says:
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.
byuu says:
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.
Instead of the legacy SDL_OpenAudio() method, we now use the newer
SDL_OpenAudioDevice() functions. This fixes audio in Windows if the SDL
version is 2.0.6 or higher.
It also allows us to use 48kHz audio for Windows (96kHz somewhat works
too, but since we don't get absolutely smooth audio with it, I'd stick
with 48kHz for now until we find a solution. 44.1Khz is available as
fallback for SDL 2.0.5 and lower. Yes, the 2.0.5 to 2.0.6 transition was
quite harsh in terms of Windows audio support...
Before performing the GB reset, we should perform a GB_save_battery.
Otherwise, resetting the emulation will kill ("kill" as in simply don't
write them into the .sav) all changes made to the battery save since
sameboy was started.
Because SDL_SCANCODE_0 comes *after* SDL_SCANCODE_9 in the SDL keycode
table, we have to check if the keycode is between >=1 and <=0. We also
have to substract SDL_SCANCODE_1 in order to set command_parameter
properly.
Errata: Currently, the savestate created with CTRL+0 is created, but
refuses to load on Windows (working fine on Linux).
