http://ufoai.ninex.info/wiki/index.php/Pk3 - claims that any file sitting out in the open as a .ufo file takes priority over anything loaded into a PK3. Is that still the case for 2.4-Dev? I've extracted and made some changes to equipment.ufo and research.ufo, but the game behavior is exactly the same.
I was trying to remove nanocomposite armor from the asymptotic market since it now requires alien materials for manufacture. I also tried to add aerial laser cannons, base defense lasers, anti-alien grenades, electrolasers, and DF stun cartridges since they're all based on terran tech. My attempt to add electrolasers as a requirement for DF stun cartridge construction similarly failed.
Do I need to package my customized .ufo files into a PK3, add a numeral to the beginning of "equipment.ufo", or something entirely different?
