The Docker/Buildroot toolchain produces 32-bit ARM binaries but the
RG35XX target runs a 64-bit aarch64 userland. Add docs/TOOLCHAIN.md
covering the full pipeline, config details, patches, and three possible
approaches to fix the architecture mismatch.

Single Makefile supports native builds (pkg-config) and cross-compilation
(CROSS_COMPILE/PREFIX env vars). Fixes -Wformat-truncation and
-Wstringop-truncation warnings at -O2 by sizing current_file to match
audio_files (256) and replacing strncpy with snprintf.

Open the joystick via SDL_JoystickOpen() when no GameController mapping
exists, fixing d-pad and face button input on devices like the Anbernic
retro handheld (GUID not in SDL's database). Handles JOYHATMOTION for
d-pad navigation and JOYBUTTONDOWN button 0 for activation.

The spritesheet is compiled in as a C byte array. An external
controls.png in cwd still takes precedence for skinning. Includes
tools/embed_png.py to regenerate the header if the asset changes.

Logs joystick enumeration at startup (name, GameController status, GUID)
and all SDL input events in the main loop to help diagnose why the retro
handheld's d-pad/buttons aren't recognized by the GameController API.

The m4a muxer doesn't support mjpeg as a regular video stream, causing
concatenation to fail when inputs contain album art. Extract art separately
and re-attach it with attached_pic disposition. Also strip leading track
numbers (e.g. "01 ") from chapter titles.

Shell script to recombine individual story m4a files back into
per-cassette files using ffmpeg concat demuxer (stream copy, no
re-encoding). Generates chapter markers from input filenames and
preserves album art.

Replace mouse input with cursor-based navigation (arrow keys / d-pad +
Enter / A button) and add app-level volume control with a persistent
vertical slider, enabling use on a handheld gaming device without mouse
or system mixer access.

Replace fire-and-forget decode_audio() with a streaming Decoder that uses
libswresample to convert planar float to interleaved stereo, fixing the
sped-up audio bug and eliminating multi-GB memory usage for long files.
Add 10-second rewind/fast-forward, stop (pause in place), position
persistence per file via positions.txt, directory scanning with file
switching, embedded album art display, and a progress bar. Handles both
old and new FFmpeg channel layout APIs via version preprocessor check.
