This is all correct! With regards to Save States (that is, a snapshot of the entire memory space of the console), yes, you need to be careful that you're using the same emulator (or "core" if RetroArch) and, sometimes even the same version of that emulator! Platform (ARM vs x86, Windows vs Linux vs Android etc) should not matter, however.For SRAM or EEPROM saved games aka the built-in save function for many games - these files are a little bit more universal and will in more cases work across emulators and such, however if possible I would not depend on this being true.If maximum portability, backup, or game continuity between home and mobile is your goal (and all are excellent use cases for cloud, here), then it will pay to use similar RetroArch configurations everywhere - it does run on just about everything, after all.
