About this app
Dolphin MMJR2 - VBI Fork
This is a personal fork of Dolphin MMJR2. Initially, the goal of this fork was to implement Sam Belliveau's VBI Skip speed hack into the MMJR2 codebase, but has since grown into a semi-actively maintained project. My primary focus is preserving the older MMJR2 user interface, which I find more intuitive and user-friendly, and support for fractional scaling while integrating features and fixes from the upstream Dolphin repository.
Disclaimer
WARNING: This fork is based on older source code! It may introduce bugs of its own and the support I can give is very limited. If you are new to emulation or prefer stability, please use Official Dolphin.
Android Requirements
OS
Android 5.0 Lollipop or higher (SDK >= 21)).
Processor
A 64-bit ARM CPU supporting arm64-v8a ABI.
Graphics
A graphics processor that supports OpenGL ES 3.0 or higher. Performance varies heavily with driver quality.
A graphics processor that supports standard desktop OpenGL features is recommended for best performance.
Dolphin can only be installed on devices that satisfy the above requirements. Attempting to install on an unsupported device will fail and display an error message.
