It should add all of them, including the two which are currently unobtainable via legitimate means.
If you have unobtainable items in your bag when playing online or using PGL, you
may be flagged for a ban which will prevent you from using all online features.
@AnalogMan's
Sun/Moon plugin doesn't add unobtainable items, and will actually remove them if they were added via another methods such as using Sasori's plugin.
@AnalogMan has created a mode3 version of
his plugin which has the same cheats as sumoHAX and more.
NTR plugins were made to disable Internet while cheats were active by design. This
can be disabled, but it seems Sasori has chosen not to (which is his right).
@AnalogMan's
plugin allows you to go online but disables battle related codes to prevent cheating. So you could have "no outlines" enabled while battling online. There are other methods you can use to remove outlines without sacrificing network functionality such as Luma's code redirection feature, or
@SciresM's patches, or Corbenik's "no outline" patch.
