Expand description

The cartridge trait. One cart model, parameterized by save type, CIC, and region (ADR 0003) — the N64 has no mapper equivalent.

Board-specific behavior — PI/SI-mediated reads and writes, save backing, optional bootstrap — lives behind it, not in the CPU. All hooks default to no-op so a board implements only what it uses.
