RPCSX ETK is a fork of a fork. The first fork is built with Claude Code on a project optimizing for Demon's Souls for Adreno 740. This fork is focused on getting Gran Turismo 5 Prologue optimized for SM8250 Adreno 650, also built with Claude Code in a similar spirit. According to tests, this Android emulator performs well against our ROCKNIX-GTK and much better against our aPS3e fork.
This ETK-tuned fork when paired with the companion core and the ETK MESA Turnip adds our GT5P road flicker fix, not yet validated upstream. It also adds a switch in Controls to fully hide the on-screen controls and restores the shader spinner to its standard form without a misaligned label.
This RPCSX emulator renders the road surfaces in GT5P with a checkerboard pattern that needs to be debugged and that is one of the purposes of this fork. It should be retired when the road surfaces render perfectly in the source project.
