libsysbase_libsysbase_a-handle_manager.o So, I optimized the MOVESETS table to only store the "overriding" bits in the movesets of the evolutions in relation to their base forms. That only improved compression slightly (about 300 bytes) I also eliminated 4 KB of IWRAM usage by libsysbase_libsysbase_a-handle_manager.o because of the "handles" buffer. We're not using it and we REALLY need our IWRAM. (and it also reduces the rom size with 4KB too!)
