Mirage 2000 5 by Rollus - weapons

On the Mirage 2000 5 by Rollus there is a weapons load system that is unique to me.
By selcting a switch you can load the aircraft model with yours choice of weapons & fuel tanks
all on the fly. And it all shows on an internal weapons screen as well..very nice..!

My question is does anyone know how this is done..?
OR has anyone seen this type of system on another FSX aircraft..?

I have a Flanker I'm trying to outfit.

thanks,

It's all XML gauges and parts of the model that are visible (or not) depending on the switch state.

No black magic, but nothing universally applicable either.

Thanks..!
