I don't have much LUA knowledge either (and that lolgoogletranslation of the Russian SW2 guide is hard to understand), I'm doing it like these guys are: editing the stuff which we think should do what it says it does, and then testing. And testing.

Missile stuff hardly overlaps anything so you should be able to throw my mod together with any other mod; the most likely collisions would be in Modules.xml if the other mod changes ship items (guns, systems, anything actually). m_modules.loc too but as those are descriptions it's no big deal (maybe confusion due to incorrect text). I'm still looking around PFX, there's some interesting stuff in those folders. Like if you want different coloured bullets, rail gun effects.
