Replace static console filter with swipeable tabs (All / Favorites /
per-console) and a collapsible search icon in the app bar. Persist
favorites via SharedPreferences keyed by ROM path. Display titles are
now cleaned (region tags stripped) for better UX while raw filenames
are preserved for cover art lookups. Sort games alphabetically and
fetch cover art in parallel (8 concurrent) for faster initial load.
Also fix PS1 controller setup so it works with both new games and save
states: pcsx_rearmed needs retro_set_controller_port_device called at
a specific point inside loadCore (between callbacks and get_system_info)
which FCEUmm crashes on. Added a "pending controller device" mechanism
that the Kotlin core can pre-set before nativeLoadCore. Save states are
now loaded BEFORE start() so the game's first frame already has the
restored state, avoiding the "controller removed" detection race.
Implement NesCore with FCEUmm/Nestopia/Mesen libretro core support.
Generalize native frontend to handle cores that require ROM data in
memory (need_fullpath=false) and move PS1-specific config out of C++
into Ps1Core. Bundle both core .so files as APK assets with automatic
extraction. Fix cover art fetching for GoodNES-named ROMs by expanding
region codes (U)->(USA, Europe) to match LibRetro thumbnail naming.
Renders the emulator framebuffer into a calculated sub-rect with
nearest-neighbor scaling and black bars, driven by the core's
reported aspect ratio. Adds a cycle button in the game HUD and
a display mode setting in the settings screen.
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.
