Detailed Description

ROM-based object dimension lookup table.

Provides accurate object dimensions for hit-testing and selection. Loads dimension data from ROM tables at:

• Bank $01: Subtype 1/2/3 tile pointers and routine pointers

Usage: auto& table = ObjectDimensionTable::Get(); table.LoadFromRom(rom); auto [w, h] = table.GetDimensions(object_id, size);
