In D&D 2nd edition, a Simulacrum is a construct made of ice or snow. It's not an actual illusion like with Mislead or Project Image, even though it's of the Illusion school of magic. A True Sight spell will only reveal that a creature is a simulacrum, but not make it disappear.

A simulacrum is treated by the vanilla game as a creature of gender "SUMMONED", probably because the developers acknowledged that such a construct had to be made preemptively and the spell we cast merely summons it from wherever we stored it. Such creatures can be sent back with a Dispel or Remove Magic, so a vanilla Simulacrum is vulnerable to these. Images are of gender "ILLUSIONARY", which both True Sight and Dispel/Remove Magic destroy.

In BG2EE a simulacrum is of the gender of the caster, meaning a neither True Sight or Dispel/Remove magic will affect it. As far as I'm concerned, the latter is a bug and the vanilla game is the correct one.
