Yes! My partner has the Super Game Boy 2 for this. It adds the link and better clock accuracy.
But Nt Mini has good sound, very clean, and very easy to work.
I hope @kevtris will release the DIY desings and adds firmware support for them. And the missing 8bit cores for the Nt Mini if possible. Too many desires ...
A new Analogue GB/GBC handled clone will be a good choice too if video output will be supported.
