wrage?

Use a different loading function for android, otherwise it would not load some functions like glad_glTexStorage2D which normally gets loaded at load_GL_VERSION_4_2 which android was probably missing, and now loads from load_GL_ES_VERSION_3_0.

A standalone function is also helpful to further separate the emulator core from the UI

Needs to check the PANDA3DS_ENABLE_OPENGL define before defining this, also likely better to put this somewhere outside of emulator.cpp

There's some code duplication (frontend_qt code also exists in frontend_sdl). I was thinking of making the initFrontend function handle that common code in emulator.cpp and call an initFrontendInternal which would be the frontend specific code defined in frontend_sdl/qt but not sure how common the duplicated code is (would it be needed for every possible frontend panda might have in the future?)

Apart from ease to adding new frontends, I think this makes it easier to create unit tests in the future. Say you want to run the emulator class as a standalone, only initialize opengl for testing. You could add another ifdef in emulator.cpp, or you could simply define initFrontend (which maybe should be named initEnvironment) in the test file to initialize the environment the way you want for your testing purposes.

Will be reopened at a later date

Can sdl_frontend.hpp include <filesystem> rq
Merging this right after

[wheremyfoodat]

Wait you included it in the .cpp not .hpp
