// We need to bypass the full Load() because it does too much (decompression etc)
// that requires valid ROM data. We just want to test the logic in Phase 4.
// However, Overworld::Load is monolithic.
// We can try to call Load() and expect it to fail on decompression, BUT
// Phase 4 happens BEFORE Phase 5 (Data Loading) but AFTER Phase 2 (Decompression).
//
// Wait, looking at overworld.cc:
// Phase 1: Tile Assembly
// Phase 2: Map Decompression
// Phase 3: Map Object Creation
// Phase 4: Map Configuration (The logic we want to test)
// Phase 5: Data Loading
//
// Decompression will likely fail or crash with empty data.
//
// Alternative: We can manually trigger the logic if we can access the maps.
// But overworld_maps_ is private.
//
// Let's look at Overworld public API.
// GetMap(int index) returns OverworldMap&.
// To properly test this without mocking the entire ROM, we might need to
// rely on the fact that we can inspect the maps AFTER Load.
// But Load will fail.
// Actually, let's look at Overworld::Load again.
// It calls DecompressAllMapTilesParallel().
// This reads pointers and decompresses. With 0x00 data, pointers are 0.
// It tries to decompress from 0. 0x00 is not valid compressed data?
// HyruleMagicDecompress might fail or return empty.
// If we can't run Load(), we can't easily test this integration.
// However, we can modify the test to just check the logic if we could.
// Let's try to run Load() and see if it crashes. If it does, we'll need a better plan.
// But for now, let's assume we can at least reach Phase 4.
// Actually, Phase 2 comes before Phase 4.
// Maybe we can just instantiate Overworld (which we did) and then manually
// call the private methods if we use a friend test or similar?
// No, that's messy.
// Let's look at what FetchLargeMaps does.
// It sets map 129 to Large.
// If we can't run Load, we can't verify the fix easily with a unit test
// unless we mock the internal methods or make them protected/virtual.
// WAIT! I can use the `OverworldVersionHelper` unit tests to verify the *helper* logic,
// and then manually verify the integration.
// OR, I can create a test that mocks the ROM data enough for Decompression to "pass" (return empty).
// 0xFF is the terminator for Hyrule Magic compression? No, it's more complex.
// Let's stick to testing the OverworldVersionHelper first, as that's the core of the fix.
// Then I will apply the fix in overworld.cc.
