The short answer is OMORI was never officially released for the Nintendo 3DS family of systems. It launched for PC, Nintendo Switch, PlayStation 4, and Xbox One. So, any “OMORI 3DS CIA” is a homebrew project—specifically, a fan-made port or conversion.
If you decide to proceed, remember to before installing any homebrew CIA. Use tools like GodMode9 to create a full system backup. And most importantly, support OMOCAT by purchasing the official game on a platform it was designed for. omori 3ds cia install
