Griffin Richards contributed to the rh-hideout/pokeemerald-expansion and celias-stupid-repository projects, focusing on core systems such as build automation, data-driven configuration, and low-level game logic. He engineered automated constant generation from JSON, streamlined asset pipelines, and refactored memory management for stability. Using C, Assembly, and Makefile scripting, Griffin introduced macros for bit manipulation and data packing, improved collision detection, and enhanced region map robustness. His work addressed bugs in battle logic and graphics rendering, while maintaining code hygiene through targeted cleanups. These efforts resulted in more maintainable, reliable codebases and smoother onboarding for future contributors, reflecting strong engineering depth.
January 2026: Focused on stability and reliability of the battle system in rh-hideout/pokeemerald-expansion. Delivered a targeted bug fix to prevent out-of-bounds access in gActiveBattler, reducing crash risk and improving user experience during battles. The fix was merged via PR #2124 (cawtds/fix-active-battler-ub) and accompanied by code reviews and safety checks. This month also reinforced our memory-safety practices and testing coverage in core combat logic.

June 2025: Focused on robustness and reliability for region data and trainer battles in rh-hideout/pokeemerald-expansion. Delivered Region Map Data Enhancements by making MAPSEC sections optional and adding explicit defaults for missing properties (x, y, width, height, name), increasing data robustness. Fixed Trainer Battle Macro Identification by ensuring consistent use of LOCALID_NONE, preventing incorrect trainer identification. Result: fewer runtime errors, more stable map rendering and battles, smoother content authoring, and a clearer commit trail for future maintenance.

May 2025 monthly summary for rh-hideout/pokeemerald-expansion focused on codebase hygiene and maintenance. Key work involved removing an unused header (map_group_count.h) that contained a static array and was no longer referenced, reducing noise in the codebase and simplifying future refactors. This change minimizes future maintenance risk and supports more efficient code reviews and onboarding.

February 2025 performance summary: Implemented automated heal location constants generation across two major repos by centralizing data into a single source and integrating automatic generation from JSON into the build. Refactored data build to reduce manual maintenance and improve consistency. Fixed a collision handling bug in PlayerNotOnBikeMoving to correctly differentiate collision types and support special cases (stopping on surfing tile, pushing a boulder) while excluding COLLISION_ROTATING_GATE to prevent unintended behavior. These changes reduce build toil, lower data drift risk, and stabilize core gameplay logic across projects.
