b078ca802f Expose SRAM pointers for frontends that manage save data their own way (#1643)
* Add a clarifying comment

- In case it saves some poor bastard hours of fruitless work

* Expose GBA and NDS save memory

- Add GetSaveMemory and GetSaveMemoryLength functions
- Where unsupported, they return null and zero

79dfb8dc8f Introduce Platform::Log (#1640)
* Add Platform::Log and Platform::LogLevel

* Replace most printf calls with Platform::Log calls

* Move a brace down

b1e4bd5520 merge local_wifi (#1516)
* 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

c3bd1d2e83 Fix reading banner from homebrew ROMs
Some homebrew ROMs do not have a banner, and use a null value to indicate this.
Do not attempt to read the banner when this is the case.

Bad Apple demo will break, because its NitroFS driver is broken. it needs a DLDI argv structure to exist in order to use its DLDI driver instead.
