int GB_save_battery(GB_gameboy_t *gb, const char *path);
In gb.h
Saves battery-backed information (e.g., battery-powered cartridge RAM or Real-Time Clock information) from the emulator instance into the file at path. Returns 0 on success and a positive errno value on POSIX failures. It will do nothing and return 0 if the currently loaded ROM has no battery-backed information.
GB_save_battery must not be called if the instance is being run in another thread, but may be called from the current one (via a callback).
