Henrik RydgårdandClaude Opus 5.5 b4ec29111b Microphone: Let the host say whether it wants polling, rather than checking for SDL
The CPU-thread polling added for SDL was keyed off defined(SDL), which
headless and Core are built with too, hence the extra headless check.
Ask the host instead, with SYSPROP_MICROPHONE_NEEDS_POLLING, so other
hosts can hand their input over the same way.

startMic now sends the same startRecording command for every non-Win32
host, taking the rate from curSampleRate like the SDL path did. The
Android path read it from param, which leaked, and which is null when
coming from onMicDeviceChange.

Build instructions
==================
See https://github.com/hrydgard/ppsspp/wiki/Build-instructions .

Also, for general information, see https://www.ppsspp.org/docs .

SDL2 Game Controller Support Notes
==================================

For SDL2 game controller support, at least SDL 2.0.4 is required.

Under the assets directory is the SDL2 game controller database: gamecontrollerdb.txt. This file contains many known control pad mappings for Windows, Linux and MAC OS. PPSSPPSDL will load this file at start-up and work out how to assign control pad buttons for your control pad.

Hot plugging of control pads is also supported.

If you control pad has a "Guide" or "Home" button then when pressed, this will trigger the emulator pause menu, thus allowing you to exit the emulator if you wish or load another game from your library.

WSL notes
=========
Works fine on WSL2 with OpenGL, at least. For more notes, see https://www.ppsspp.org/docs/development/wsl/ .

Running with valgrind
=====================

Here's an example where we both use suppressions, and generate new ones (that you can then take from suppressions.log and simplify and copy to valgrind-wsl2.supp):

> valgrind --suppressions=SDL/valgrind-wsl2.supp --gen-suppressions=all --log-file=suppressions.log build/PPSSPPSDL

Running with ASAN
=================

./b.sh --sanitize

build/PPSSPPSDL.app/Contents/MacOS/PPSSPPSDL

Running with UBSAN
==================

./b.sh --sanitize --sanitizeub

UBSAN_OPTIONS=print_stacktrack=true build/PPSSPPSDL.app/Contents/MacOS/PPSSPPSDL
