Using "exit retroarch" just reloads the .nro file if you use the NSP, I think that it's necessary to avoid crashes. Also, that function is helpful to avoid corruption when using the NRO version and exfat (at least, for me exiting retroarch/other HBs just by pressing HOME always left me with corruption, using the proper "exit" always avoided that. using the NSP avoids crashes for me but "Exit" funcion is useless)When using the NSP, I can't exit RetroArch without using the home button. When I use the menu and select exit, the screen goes black and then RetroArch reloads.
