+
+notes: |
+  Commercial fantasy consoles by Lexaloffle Games LLP. Closed-source binaries
+  distributed as ZIP archives from lexaloffle.com (requires purchase).
+
+  Batocera configgen (lexaloffleGenerator.py) handles both systems via a single
+  generator. PICO-8: binary at bios/pico-8/pico8. Voxatron: binary at
+  bios/voxatron/vox. Generator checks binary existence and executable permission,
+  raises BatoceraException if missing. LD_LIBRARY_PATH set to the BIOS directory
+  for shared library resolution.
+
+  Each distribution ships a statically linked binary (pico8/vox) and a dynamically
+  linked variant (pico8_dyn/vox_dyn). Batocera uses the static binary. The .dat
+  file is loaded at startup and contains boot sequence, themes, and internal data.
+
+  PICO-8 supports x86_64 and ARM (Raspberry Pi). Voxatron x86_64 only.
+  Voxatron depends on libHoloPlayCore.so (Looking Glass SDK), compile-time linked.
