* attempt at betterer wifi
* add preliminary sync mechanism
* fix gaps in wifi implementation
* move local-MP comm to its own module instead of cramping Platform.cpp
* remove some stupid cruft
* as you wish, Sorer
(starting work on shared-memory system)
* shared-memory IPC that actually works (albeit Windows-only for now)
* shut up logging from NULL writes on ARM7 (ffs Nintendo learn to code)
* get this somewhat good
* leave client sync mode when host deauths. makes download play actually work.
* start implementing MP-comm error handling
* * add MP-reply error counters
* feeble attempt at fixing slowdown/desync/etc problems
* somewhat better exchange/sync method
* * when entering power-saving mode, be sure to finish transferring the current frame first
* fix misc bug due to old cruft leftover
makes for a more stable connection
* remove a bunch of cruft
* set wifi time interval to 34 cycles instead of 33. games seem sensitive to the general timing of wifi vs the rest of the system, and this seems to make things run better, atleast until I rewrite this to use a proper scheduler.
* more graceful handling of disconnects
* deal with FIFO overflow more gracefully
* BAHAHAHAHAHAHAHAHHHH
THE SNEAKY BASTARDS
so, when the DS receives a beacon with the right BSSID
that beacon's timestamp is copied to USCOUNTER
* attempt at making the connection process smoother for weird games
* * begin adding POWCNT2, only applies to wifi for now
* begin work on wifi scheduler
* implement the shitty timers
* add the RF wakeup thing
* begin work on receiving frames. for now it can just receive melonAP beacons, but hey, it's a start.
* add enough TX functionality that online wifi is a possibility again.
* there are problems with this scheduler thing. committing it anyway
* kind of a rollback... we're gonna work out a compromise on this, I guess
* don't transmit shit if RXCNT.bit15 isn't set
* move RX-finish to its own function. more accurate filtering. implement RXFILTER.
* remove some cruft
* fix some of the shittiness when trying to connect more than two players
* fix some more shittiness
* fix more wifi shittiness (mainly don't try to receive shit while sending a frame)
* run wifi every 8µs. improves performance.
* fix IRQ14/IRQ15
* make this work under Linux
* Make it work on macOS, for now using a custom sem_timedwait
implementation.
If anyone knows anything about mach ports and have an idea for how to
make this work using mach IPC, please do let me know.
* 25ms seems like a good timeout
* begin work on proper multiplayer UI shito.
for now, determine a global instance ID, and derivate the system MAC from it. remove 'randomize MAC' option.
* finish removing RandomizeMAC
* lay groundwork for instance-unique config
* work some on the UI... make it not labelled Fart
* more UI work: make it explicit that some things are instance-unique
* separate firmware files for multiplayer instances
* make instances save to different save files, too
* more UI work, make things somewhat less shitty
* lay base for the multiplayer settings dialog
* actually hook up most of that dialog
* actually implement the fun audio settings
* ensure all the wifi shit is properly savestated and reset. properly update timings for the wifi region when wifi is disabled.
* add more fun labels
* * ignore WEP frames if WEP is off
* implement RX_LEN_CROP
* fake enough of WEP processing to make Inazuma Eleven work
* * do not copy more ROM banner data than actually needed
* avoid trying to read out of bounds if the banner offset is bad
* Fix oversight with the preferences action causing the build to fail on macOS

also including:
* getting rid of shitty strings
* all new, cleaner ROM handling code
* base for DSi savestates
* GBA slot addons (for now, memory cart)
* make timers usable for measurement shito without being assfuckingly unreliable
* bürp
* Arisotura can you ever clean up your goddamn code
also regroup the timer code instead of having it split weirdly
* make the set-timing functions a tad less hacky
* congrats Arisotura you made an ass-enum
* add timing region tables, and separate timings for ARM9 DMA (exempt of 3c penalty)
* temp work on DMA timings, not finished
also, did you know? 'increment/reload' is also a thing for the source address
* begin work
* add some of the GBA slot/wifi timings
* complete it, I guess
* make some progress
* getting somewhere
* sdsdfs
* see, Arisotura, was it that hard? blarg.
* SCFG_BIOS now selects between NDS and DSi BIOS
Allowing experimental direct boot.
* - making NWRAM Priorities work as in the HW
- fixed loading DSi stage2 Bootloader when in direct boot (should not be loaded) and might interfere with the image loaded into the (N)WRAM previously
* NWRAM and SCFG Registers are now write-guarded by the corresponding SCFG_EXT7/9 Bits
* removed debugging remainder
* Moved NDSHeader dependent SCFG initialization into the new DSi::SetupDirectBoot function called from NDS::SetupDirectBoot when ConsoleType is DSi
* removed redundant SCFG_BIOS bit checks
* Set of changes from RSDuck's review
* removed a forgotten comment
* - removed the guarded debug outputs for NWRAM
- NWRAM writes to bank and window registers now apply their write masks.
- added comment on an existing TODO within the code describing, why this is OK
- fixed initial NWRAM bank reset just accessing set A
* NWRAM not mapped to 03... range if bit25 in SCFG_EXT is cleared
* removed NWRAM write block on cleared bit25 in SCFG_EXT
* changed type of iterator for MapNWRAM_x functions from s8 to int
* - reduced calculations/comparisons on NWRAM write operations
- changed u8 to unsigned int for an iterator MapNWRAM_x

* Implement NO$GBA debug registers.
NO$GBA comes with 4 debug registers that allow a ROM to print text to
the emulator terminal and 2 other status registers, one with the name of the
emulator and the other with the clock cycles count. This commit
implements them for the ARMv5 processor.
Some small things to note:
- `NocashPrint` was changed and now it takes an address to _the string_ instead of the flags before it (those
don't do anything anyways).
- The "Emulation ID" register contains the string "melonDS " followed by version, _not_ "NO$GBA"
* Fix styling issue and improve comment regarding NO$GBA message flags
* Fixed division edge case: Div64/32 and Div64/64 set the remainder to 0 if dividend == INT64_MIN && divisor == -1
* Fixed CPU edge case where ARM9 ALU ops would switch to Thumb even when they shouldn't
* Only clear the lowest bit of the jump address in ALU ops with rd==15 (on recommendation of RSDuck)
* Draft GPU3D renderer modularization
* Update sources C++ standard to C++17
The top-level `CMakeLists.txt` is already using the C++17 standard.
* Move GLCompositor into class type
Some other misc fixes to push towards better modularity
* Make renderer-implementation types move-only
These types are going to be holding onto handles
of GPU-side resources and shouldn't ever be copied around.
* Fix OSX: Remove 'register' storage class specifier
`register` has been removed in C++17...
But this keyword hasn't done anything in years anyways.
OSX builds consider this "warning" an error and it
stops the whole build.
* Add RestartFrame to Renderer3D interface
* Move Accelerated property to Renderer3D interface
There are points in the code base where we do:
`renderer != 0` to know if we are feeding
an openGL renderer. Rather than that we can instead just have this be
a property of the renderer itself.
With this pattern a renderer can just say how it wants its data to come
in rather than have everyone know that they're talking to an OpenGL
renderer.
* Remove Accelerated flag from GPU
* Move 2D_Soft interface in separate header
Also make the current 2D engine an "owned" unique_ptr.
* Update alignment attribute to standard alignas
Uses standardized `alignas` rather than compiler-specific
attributes.
https://en.cppreference.com/w/cpp/language/alignas
* Fix Clang: alignas specifier
Alignment must be specified before the array to align the entire array.
https://en.cppreference.com/w/cpp/language/alignas
* Converted Renderer3D Accelerated to variable
This flag is checked a lot during scanline rasterization. So rather
than having an expensive vtable-lookup call during mainline rendering
code, it is now a public constant bool type that is written to only once
during Renderer3D initialization.
