The X-ARAPUCA are a family of novel devices that are able to detect scintillation light from noble elements. This technology is currently in use by huge Liquid Argon Time Projection Chamber (LArTPC) experiments dedicated to neutrino physics, including the Short-baseline Near Detector (SBND) at Fermilab. In each experiment, the X-ARAPUCA assumes a different form factor better suited to the detectors' geometry, which is a statement of its versatility. Here we present the status of an ongoing effort to develop an unified simulation able to describe any and all X-ARAPUCA devices, the ArapucaSim. By introducing new strategies for simulating the wavelength shifting and dichroic materials, the heart of the X-ARAPUCA, we achieved the desired precision and short turnout times needed for ArapucaSim to become an essential tool in the X-ARAPUCA R&D cycle. We also present the validation procedures based on data from multiple prototyping phases and tests.
