Dec 1, 2025December 2025 focused on expanding battle mechanics, improving debugging workflows, and strengthening test coverage for the pokeemerald-expansion project. Key features delivered include cross-use of items in double battles and new debug menu actions (Give Egg and Set KO). Major maintenance and quality improvements were achieved via the Teachable Learnsets generation refactor and targeted code cleanup work. Testing coverage was expanded with lum berry multi-status tests and max-stage tests for Intrepid Sword/Dauntless Shield, supporting more robust balance checks. Collectively, these changes reduce edge-case bugs, improve user experience, and strengthen the foundation for future releases, while demonstrating proficiency in C/C++, battle logic debugging, and test-driven development.
