The longer answer: A truly “Extra Quality” Binding of Isaac: Rebirth ROM for 3DS does exist in private collections—specifically repacks that merge the 2016 eShop version with community-made overclocking patches and undub audio. However, the base game’s charm lies in its grit. The 3DS version is not supposed to be buttery smooth; it’s supposed to feel like a cursed relic running on half-melted hardware.

If you own the 3DS version via a prior eShop purchase, dumping your own cartridge or digital title using GodMode9 is the only 100% legal way to obtain an “Extra Quality” ROM. The scene’s “Extra Quality” releases are often just optimized dumps of what you could theoretically back up yourself. The short answer: Yes, but it’s overkill.

Yet, it did. And it did so with stereoscopic 3D support that no other platform could replicate.
