I’m looking on archive.org
There’s
[V2] Notelu’s Song Of The South Restoration
This is regarded as the best version out there. Added on there in 2018.
I also see
Song Of The South (4K Restoration)
Added in 2021. But honestly looks inferior to the V2 Notelu at least in terms of color. And may even be in upscale I don’t know.
Am I missing another better version?
