Hello sedenion, in the links you used as documentation you are mainly using 2000D and 2000-5 HUD symbology... The BGS(Boitier generateur de Symboles) on those types are not the same at all (Mirage 2000D and -5 Versions are similar, and B/C/N versions are the same).
I can also notice that Razbam did not implemented the "Radar Slaving"" mode on the Magic missile (making appear a triangle and a specific tone). The tone can be found in the Mirage 2000 Sound folder, but no such function in flight. could be a nice addition to your mod.
