During May 2025, Francisco Prieto expanded SNES and Super Famicom compatibility in the finalburnneo/FBNeo repository, focusing on emulator development and game preservation using C++. He delivered support for new games and regional variants, including prototypes and homebrew titles, by updating the d_snes.cpp module to handle additional entries and region-specific behaviors. The work emphasized code quality, maintainability, and traceability, ensuring future regional releases could be integrated smoothly. Although no major bugs were addressed, Francisco’s contributions deepened the emulator’s catalog coverage and reproducibility, providing a robust foundation for quality assurance and ongoing development within the C++ codebase.
