Vortex Decoder Options (URNT12)


Add informative information in addition to the normal output.


Using this mode, the decoder will reject the output if it can't decode every single item, exluding the remarks section which often has data that our decoder cannot decode, and makes sure that every item is there, unless the vortex is noted as abbreviated. Without this mode, the decoder will simply present the undecoded data in the output and not check to see if every item is there. Strict mode is not recommended.
