Numero - RetroBIOS¶
Technical 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.
