If I am understanding this correctly, TN-V has sound for PSX games and ARK doesn't. Also, TN-V I can play CSO/ISO backups but if I wanted to play emulators I have to enable the game2vhbl plugin? So I can't jump from one to the other without restarting TN-V? But with ARK it allows you to play between PSP backups and emulators without restarting?
