During December 2025, this developer delivered the ChooseBoxMon feature for the rh-hideout/pokeemerald-expansion repository, enabling players to select Pokémon directly from storage boxes for interactions such as trading and move tutoring. The work involved updating event scripts across multiple in-game locations to support the new storage interaction flow, streamlining user experience by reducing manual navigation steps. Using C programming and event scripting, the developer consolidated changes into a single commit, ensuring maintainability and clear documentation. The focus on game mechanics and user workflow resulted in a more efficient in-game process, enhancing interaction efficiency without introducing new bugs during the development period.
