This presentation explores how online retro gaming communities reconstruct the aesthetic value of sonic glitches, shifting them from technological errors to coveted musical artifacts. While traditional ludo-musicological frameworks largely analyze video game sound through the lens of intended player input and deterministic design (Collins 2013; Summers 2016), this approach overlooks the vibrant, participatory culture of "glitch hunting" and speedrunning. Focusing on Pokémon Yellow Version (1998), this digital ethnography investigates how player communities across both English and Japanese online spaces evaluate and celebrate audio anomalies, specifically the "Red bar glitch" and encounters with glitch entities like "MissingNo." and "C1."

In Japanese RTA (Real Time Attack) communities, where system exploits intersect with the culture of urawaza (secret tricks), and within English-speaking speedrunning networks, unpredictable sonic phenomena are not discarded as programmatic failures. Instead, stochastically generated timbres and emergent rhythmic complexities are actively encouraged and prized. They serve as coveted auditory markers of successful systemic manipulation and shared community knowledge. Drawing upon actor-network theory (Latour 2005) and extending concepts of "vibrant matter" (Bennett 2010) into digital social spaces, I argue that the glitch engenders a distinct, cross-cultural value system.

By analyzing transnational community discourse and shared gameplay recordings, I demonstrate how players collectively renegotiate the boundaries of the intended ludo-sonic environment. Ultimately, this presentation illustrates how these communities construct a post-humanist sonic aesthetic where the deterministic architecture of the game code is subverted, and the technological "error" becomes a celebrated site of shared cultural meaning.
