notes: |
  Libretro port of Wabbitemu, a TI-83 family calculator emulator.
  Supports TI-83, TI-83 Plus and TI-83 Plus Silver Edition.

  A calculator ROM dump is required. The core searches sequentially in the
  system directory (libretronew.cpp:575-594): ti83se.rom first, then
  ti83plus.rom, then ti83.rom. The first found is loaded via rom_load()
  (libretronew.cpp:608). file_present_in_system() checks existence only
  via VFS open/close (libretronew.cpp:451-472). No hash or size validation.

  Without any ROM, the core shows a blank screen listing the expected
  filenames (libretronew.cpp:1030-1042). No HLE fallback.

  Supports no-content launch (libretronew.cpp:556). Content files
  (.8xp/.8xk/.8xg) are loaded on top of the running ROM via link cable
  simulation. Auto-saves calculator state every 10 seconds
  (libretronew.cpp:1050-1063).

  Upstream Wabbitemu supports a wider model range (TI-73 through TI-84+CSE)
  but the libretro wrapper only searches for TI-83 family filenames. The
  underlying engine (calc.cpp:rom_load) auto-detects the model from the ROM
  header.
