>>45563759Regarding Beta P2:
"For some reason, the map matrix for the interior of the P2 Lab contains - most likely due to an error - a connection to this map, which appears to be an early Nuvema Town. The layout is very similar to the final version, though the geometry is simpler and the front shoreline lacks any of the detail present in the final version. The collision suggests that there was also a different model for the Lab, but that has yet to be found, and the models for what are apparently supposed to be the houses and the lab have been replaced by the parasol and table respectively. The map is apparently a very early version of the one that was included in the released game; none of the final tilesets fit it. Tileset 02 is the closest thing to a match, but the textures have clearly changed considerably since this map was made. This area also exists in Black 2 and White 2."
