- Remove android:background from C64DisplayView: SurfaceView's XML
background painted over the surface, hiding all rendered content
- Fix pixel byte order: copyPixelsFromBuffer reads [R,G,B,A] bytes, so
physical colors must be packed as ABGR (not ARGB) to avoid R/B swap
- Fix six wrong C64 keyboard matrix positions (1, 2, Q, E, R, Y) taken
from the authoritative VICE hardware matrix table
Assets (ROMs and disk images) now live in getExternalFilesDir, making
them accessible via USB file transfer and any file manager app without
adb or root.
- "Import ROMs" button walks through kernal/basic/chargen picks in
sequence and restarts the emulator when done
- "Import Disks" button opens a multi-select picker; files are saved
as SCHWUM<N><P>.D64 (uppercased for consistent lookup)
- 2×4 episode grid (1A–4B) lights up each button as its disk image
becomes available; tapping loads that disk into drive 8
Cross-compiles VICE 3.8 headless for ARM64 and x86_64 as part of the
Android Studio build (Gradle buildVice task + build_vice.sh). The JNI
bridge (vice_jni.c) renders frames into a shared framebuffer read by
C64DisplayView, and forwards key events from C64KeyboardView to VICE's
keyboard matrix. Without ROM files the app shows a placeholder blue
screen; with ROMs and a .d64 disk image the full C64 emulator runs.
