Cores with straight stdio file I/O

inactive123 commented 3 years ago

These cores will need to have straight libc file I/O calls replaced with libretro-common VFS equivalents:

We probably won't make this for 1.9.10, so we can just see where we arrive at before the end of Friday and then move the rest over to 1.9.11.

I will start pulling my weight here too.

Pokemini should be added to the list.

Also, while PUAE and VICE do make use of VFS routines, they don't call RETRO_ENVIRONMENT_GET_VFS_INTERFACE - which means they won't necessarily see benefits on Android or UWP platforms. I don't know if any other cores are affected by this (although it should be a trivial fix in each case)
