Developed and integrated a custom exit button feature for the EmulatorJS player within the rommapp/romm repository, replacing the default exit control to enhance user navigation. The implementation ensured that emulator state was saved before redirecting users back to the previous page, streamlining the emulation exit process and improving overall user experience consistency. Leveraging frontend development skills with JavaScript, Vue.js, and CSS, the work focused on seamless UI behavior and maintainable code structure. Comprehensive documentation accompanied the integration, supporting efficient quality assurance and future updates. No major bugs were addressed during this period, with efforts concentrated on feature delivery and UX refinement.
