The PS2 emulator NetherSX2 released update 2.1, improving performance and fixing regressions and visual bugs. The update includes fixes for popular games like Jak, Grand Theft Auto: San Andreas, Metal Gear Solid 3, and Timesplitters. There are two versions of the update available for download, each based on different versions of AetherSX2. Users can choose between the two builds on GitHub, but only one build can be installed at a time and saves are not cross-compatible. NetherSX2 remains a reliable option for PS2 emulation on Android devices.
