| `crates/gba-core/src/memory/audio_step_tests.rs` | Audio access phases, shadow validation, and CPU/DMA failure rollback |
| `crates/gba-core/src/io/inactive.rs` | Disconnected serial initialization with explicit unsupported-activity validation |
| `crates/gba-core/tests/inactive_devices.rs` | Device masks, wave RAM, GPIO pull-ups, serial data, and failed CPU/DMA write isolation |
| `crates/gba-core/tests/serial_control.rs` | RCNT mode gating, inactive bits, byte/halfword lanes, CPU/DMA diagnostics, and interrupt isolation |
| `crates/gba-core/src/io/timer_step.rs` | Staged timer/audio state, divider phase, timer IF bits, and sound refill requests at ordered CPU/DMA bus phases |
| `crates/gba-core/src/memory/timer_step_tests.rs` | Timer access phases, coherent lanes, cascades, IF ordering, rollback, DMA, idle, and clock ownership |
| `crates/gba-core/src/display.rs` | Display clock, scanline status, comparison edges, and display IRQ events |
