Abstract This paper examines AetherSX2, an open-source PlayStation 2 emulator for Android, focusing on its system architecture, emulation strategies, performance optimizations for mobile hardware, user experience considerations, and legal/ethical issues. We evaluate how AetherSX2 translates PS2 hardware behavior to modern ARM-based SoCs, the trade-offs between accuracy and performance, and implications for preservation and homebrew communities.
This introduces a paradox: emulation advocates celebrate preservation and access, but the friction in setup tends to favor technically literate users—those who already have the know-how to navigate legal and technical gray areas. If mobile emulation is to broaden access responsibly, future efforts must prioritize streamlined, safer workflows and better in-app guidance.
