Worked on the SirzBenjie/pokerogue repository to deliver a targeted data-cleanup feature focused on sprite color data. The approach involved removing redundant color entries from variant JSON files across front, back, and experimental sprite categories, including female variants, to streamline asset management and improve data maintainability. By aligning color definitions and refactoring the color data model, the work reduced inconsistencies and simplified future updates. The implementation relied on JSON manipulation and data cleaning techniques, resulting in a single, reviewable commit that enhanced data efficiency. This contribution addressed quality-of-life improvements for ongoing development and ensured greater integrity of sprite color assets.
