A detailed walkthrough of reverse engineering and patching the Nintendo Wii's News Channel to display local Puerto Rican news in 2025. The project involved extracting and modifying WAD files to redirect hardcoded URLs, forking WiiLink's open-source news generator to add El Nuevo Día as a source, and automating hourly updates using AWS Lambda and EventBridge.
