Hi gusmandb,
Thanks for all your help. I definitely assumed a dedicated VR system would be a much better experience, but to be honest, I'm not much of a modern gamer. So I only wanted something easy and accessible to try 3DNes in VR because I wouldn't be using the VR system for anything else. So buying a dedicated system specifically for 3DNes seems a tad excessive, hence my attempt to go the mobile headset route. But from what you're saying, that route will always produce shitty results, so thanks for letting me know before I wasted my time trying other headsets in vain. I appreciate it.
