Worked on the shadps4-emu/ps4_cheats repository to enhance the emulation experience for Persona Dancing Games by focusing on both performance and visual fidelity. Used Assembly and reverse engineering techniques to patch the startup sequence, enabling the emulator to skip boot logos and thereby reduce startup time. Enforced a 4K render resolution, improving the visual quality for users. The work centered on game hacking and patching, delivering a single feature that streamlined onboarding and increased perceived polish without addressing bug fixes. These targeted changes contributed to a more robust rendering pipeline and a faster, higher-quality startup process for end users.
