Adds app-side support for the ESP32-WROOM-32 Joy-Con bridge over USB
serial. The ESP32 pairs with the Joy-Con via Bluetooth Classic (using
Bluepad32), parses input reports, and streams an 11-byte wire protocol
frame at 60 Hz over the CP2102's USB-CDC serial connection.
ControllerManager now auto-detects known USB-serial chips (CP2102,
CH340, Espressif native USB) by VID/PID, opens the port at 115200 8N1
via usb-serial-for-android, and parses incoming frames into the same
dispatchButton / onAnalogEvent pipeline used by all other controller
paths. Frame format: [0xA5 sync] [seq] [btns_lo] [btns_hi] [dpad hat]
[lx] [ly] [rx] [ry] [flags] [XOR crc8].
Verified stable for 10+ minutes with zero disconnects on the Samsung
Fold 6 — the 8BitDo USB adapter wedged within 2 minutes on the same
phone. Full firmware control eliminates the OTG selective-suspend issue
that plagued the adapter path.
Downloads box art from libretro-thumbnails GitHub repos for all
supported consoles (PS1, NES, SNES, N64, Genesis, PS2). Art is
fetched in the background on first scan and cached locally. Also
fixes multi-track .bin files showing as separate game entries.
Jetpack Compose app with adaptive layouts (phone/tablet/foldable) using
Window Size Classes. Integrates a C++ libretro frontend via JNI for
actual PS1 emulation using pcsx_rearmed, with AAudio output and
ANativeWindow rendering.
