There is a plugin that lets Pokemon Dream Radar transfer Pokemon to SD card saves instead of cart, does it affect legality?

Has anyone used it? Would the Pokemon be exactly the same as if they transferred to a normal cart?

There shouldn't be any difference.
The Pokemon are not generated by the Dream Radar, it just sets some flags to the game to tell which Pokemon to generate. So even if these flags get set by a tool/plugin or whatever the Pokemon will be generated legal in the end.
