Complete callable reference

This index covers every public callable declared under include/mobigo_sdk/. It is organized by ownership and runtime layer; each linked page gives exact C signatures, return conventions, storage lifetime, and evidence boundaries.

Reference	Headers covered
Runtime, input, and controls	application.h, resident_runtime.h, input.h, resident_input.h, resident_keys.h, touch.h, resident_touch.h, system_controls.h, standard_controls.h, direct_controls.h
Graphics and resources	resource_bundle.h, resource_graphics.h, ui_family_b.h, settings_overlay.h, resident_resources.h
Audio and storage	audio.h, audio_resources.h, resident_audio.h, resident_storage.h
Low-level hardware	hardware.h, with memory constants from memory_map.h

The remaining public headers are declaration/configuration surfaces rather than callable families:

• mobigo_sdk.h is the umbrella include;
• resident_addresses.h centralizes supported resident word addresses;
• resident_backend.h exports the target backend object used by controls;
• memory_map.h defines title-RAM ranges and overlap macros.

Target language and ABI

Application code is C. The bundled target builder accepts C99-style .c and u'nSP assembly .asm/.s sources. It does not provide a target C++ frontend, and the public API does not establish a C++ ABI. Emulator2 is a separate host program written in C++20; that does not make C++ a supported MBA language.

All signatures below are clean-room API contracts, not recovered vendor symbol names. Word-addressed pointers, target-only calls, resident handles, and host-portable authoring helpers are labeled separately.
