- Save Editor: Implement full Gen 3 FireRed save editing including PID/personality, IVs/EVs, natures, ability slots, gender, shiny toggles, held items, Pokédex flags, and event/trainer toggles. - Scripting & Specials: Add Pokédex rating evaluations, Magikarp/Heracross size records, Trainer Fan Club tracking, and FireRed event flag mappings. - Overworld & Rendering: Interleave metatile and actor draw calls by row bucket with OAM elevation priority sorting for bridges and overhead layers. - ROM Extractor: Parallelize Gen 3 extraction across 4 concurrent love.thread workers with love.filesystem searchers for cross-platform support (Switch/Xbox/Mobile/Desktop). - LZ77 Decompressor: Accelerate GBA LZ77 with preallocated FFI buffers and 0-based displacement indexing ensuring 100% byte-for-byte asset parity. - Testing: Add unit test suites for LZ77, size records, Pokédex rating, Fan Club, elevation priority, Seafoam puzzles, and Gen 3 save editor operations.
