Me to the rescue again lol
Ok you need to update your Spec.rci file
1) Download the file
Spec-RCI_Generate_Batch_File.rar
2) Extract it to your XWA DIR
3) Rename or delete the Spec.rci
4) Run the Spec-RCI Generate Batch File.bat
5) XWA will start, now enter the Tech Library, it'll take a little while for the craft to load.
6) Exit XWA you'll see a new Spec.rci has been created, hopefully if you enter the skirmish screen the new Z-95's will have missiles, If this fails repeat
If this fails to work Download Jeremy's
XwaSpecRciEditor
1) Extract it anywhere you like
2) Run XwaSpecRciEditor.exe you'll find the Spec.rci in your XWA DIR open it
3) Scroll down to the craft you installed, if you look at Missile for that craft it might say 0, you will have to change this.
4) So if you have MXvTED handy, open it and got the the same craft slot click on the Weaponry tab and look at the 1. Missile Load, there should be a figure there.
5) Enter this figure in the Spec.rci file you have open
6) To save the file, DO NOT just click Save As, first you will have to go to your XWA DIR and Delete the Spec.rci manually, then and only then click on Save As, it will create a new file
7) Test in Skirmish to see if your craft now has missiles.
If you wish to edit any more craft, remember to open the Spec.rci make the changes, delete the Spec.rci and then Save As, for some reason when you try to just click Save As and overwrite the Spec.rci the changes are not saved, weird.
Anyhow have fun, hope it works
