One more observation: I think the installer could be a bit more elaborate on the some options. "Rebalance also armor on PC" or "Changes in critters" doesn't tell much, for example. "New items" is being mentioned in at least 3 options, maybe they should've been made mutually exclusive?
Burn, the Mr.Fixit ini provided in Phobos' mod is easily modifiable.
I searched for ini files, and I don't see that. Which file do you mean?
Sorry, it's in \text\english\dialogue. It's called test0.msg in my folder. It may just be test.msg. In it you will see all of the crafting recipes. If you want to add in a turbo plasma rifle, it would look like this:
{4500}{}{[ITEM]}
{4501}{}{233} # Item PID for the Turbo Plasma Rifle, this is what you will craft.
{4502}{}{pcx/items/turboplasma.pcx} # Item inventory frame
{4503}{}{170060}
{4504}{}{CRFT_EL2} # craft electronics, you will need the stage 2 electronics crafting ability
{4505}{}{190000} # 5 h 00 m - time to craft
{4506}{}{NO}
{4507}{}{10} # Weapons - it's in the weapons (10) category in Mr. Fixit
{4508}{}{[TOOLS]} # The items you need to craft the weapon (not consumed, only need them in inventory)
{4509}{}{228} # PID_TECHNICAL_MANUAL
{4510}{}{308} # PID_SUPER_TOOL_KIT
{4511}{}{73} # BIG BOOK OF SCIENCE
{4512}{}{[SKILLS]} # Skills required to craft
{4513}{}{SKILL_REPAIR:120}
{4514}{}{SKILL_SCIENCE:120}
{4515}{}{SKILL_ENERGY_WEAPONS:120}
{4516}{}{SKILL_SMALL_GUNS:120}
{4517}{}{[COMPONENTS]} # Consumed items required
{4518}{}{15:1} # Item number for the standard Plasma Rifle, this item is used up.
So now, if you have a Plasma Rifle, Super Tool Kit, Technical Manual and Energy Weapons, Small Guns, Repair and Science at 120, you can craft the Turbo Plasma Rifle.
That's the jist of it. You may need to create the .pcx image files since they may not be in your items folders.
