duckstation-ext-mac VS libretro-super

Clone the macOS externals repository (for MoltenVK): git clone https://github.com/stenzek/duckstation-ext-mac.git duckstation/dep/mac.

git clone https://github.com/stenzek/duckstation-ext-mac.git dep/mac

So no more need to reboot and this is awesome, but why install another app when Retroarch is so convenient? It is so cool to have all old games in one place, and it even has Duckstation core. Seems like the build of Libretro core just doesn't include this branch which is essential for Vulcan on Mac to run.

1. brew install cmake sdl2 qt5 (from terminal if you have homebrew installed) 2. git clone https://github.com/stenzek/duckstation.git -b dev 3. cd duckstation 4. git clone https://github.com/stenzek/duckstation-ext-mac.git dep/mac 5. cmake -DCMAKE_BUILD_TYPE=Release -DQt5_DIR=/opt/homebrew/Cellar/qt@5/5.15.2/lib/cmake/Qt5 . 6. make -j8 7. cd bin 8. codesign --force --deep -s - Duckstation.app

For reference, I was told that the latest build of MAME can be gotten through here: https://github.com/libretro/libretro-super

Before I knew this, I informed myself on the documentation for each core: https://docs.libretro.com/library/mesen-s/ But the description is more informative for quick overview. The description is from the .info files, in example in https://github.com/libretro/libretro-super/blob/master/dist/info/mesen-s_libretro.info on the bottom line that starts with description =

Are you missing your core info files? The core info files tell Retroarch which cores support save states. You can download them from the Online Updater or download them manually and put them in the correct directory. To check which directory they go into check:

The source is available here: https://github.com/jamsilva/chimerasnes. I made a merge request to libretro-super so that the core can be automatically built (https://github.com/libretro/libretro-super/pull/1701) but it's probably not going to be available until the next release of RetroArch.

It might be somewhere here or in libretro-super.

In any case I grabbed todays 'nightly' build from here and updated the core info file from here. The nightly core runs fine on the Mini but while the options for save states do appear in Retroarch, they do not function (saving or loading a state results in an onscreen message that states are not supported).

PCSX2 can't load .cue file, it should be removed from the compatible extensions, I even proposed a fix a while ago so that core doesn't appear anymore when selecting a .cue: https://github.com/libretro/libretro-super/pull/1569
