Thank you for the explanation. I'll keep the retro duo for casual playthroughs of other games and do my speedrunning on the NES classic for now.

Hi, everybody. I read the list of acceptable hardware and saw that the Analogue NT mini is approved. I have a Retro Duo that (I believe) is essentially the same idea--it is a modern hardware console that plays original NES or SNES cartridges. Is the Retro Duo allowed for speedruns? If not, what is the difference between it and the NES / Analogue NT?

Thank you for explaining. My current runs are with the NES classic mini, but I wondered if the Retro Duo would be allowed or even better because the frame rate might be the same as the NES instead of 60.00 on the NES classic.
