Changing level of a hardpoint...Go into shiparch.ini, you'll need to decompress the .ini using a decoder or installing SDK before. Find the ship you want to edit, and look at the bottom of its entry, you'll see a line similar to this
hp_type = hp_gun_special_9, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05
Keep "hp_type =" the same. Copy the line, and paste it above the others (just for organization). Change the number to 10 (or whichever level you want the hardpoints to be) and type in HpWeapon## for however many guns there are on the ship, i.e., if there are 6 weapons you want at level 10, you'll need to add 6 of them, so it would look like this;
hp_type = hp_gun_special_10, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
Also, you'll need an entry like that for every level of weapons you want on the ship. If you want all the guns to be level 1-10, you'll need it to look like this.
hp_type = hp_gun_special_10, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_9, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_8, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_7, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_6, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_5, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_4, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_3, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_2, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
hp_type = hp_gun_special_1, HpWeapon01, HpWeapon02, HpWeapon03, HpWeapon04, HpWeapon05, HpWeapon06
To change the energy drain of a weapon you'll need to access weapon_equip.ini. in the Gun section of the weapon, look for the line;
power_usage = #
Change the digit to whatever you want and save the file. There is no special equation for power usage, the number you enter is the amount of power it drains. That simple
