Hyperkin Retron1 is accepted as the “HD” version but no longer as the “AV” version.
It is only the “Retron1 HD” version that has NTSC/PAL switch and by so force the 50 hertz & PAL colour format.
The “Retron1 AV” is apparently locked in NTSC mode and was an oversight.
We apologise for any inconvenience this might cause.
