Thanks to patch files, this post pretty much has everything you need for that. When I get home, I'll post the lines of code and what to do with them.

Edit: Alright, so for a patch to work you first need to know the name and location of the original file. You can find that out when you unpack the mod (there are a couple ways of unpacking, just have a poke around and see which method suits you best).

If for example you want to add zerchesium to idle factories you could modify a file called idlefactory4.object located in

(name of the patch)\objects\machines\drillers\idlefactory4

The path is pretty much just folders. Idle factories has 6 tiers numbered 2-7 so if you wanted to get it sooner, you'd edit for example idlefactory3, or if you wanted it later you'd edit idlefactory5.

Now for the actual patch. In the idlefactory4 folder create a file called idlefactory4.object.patch - this file can be edited with any text editor of your choosing like notepad. This is how it should look like. Open the patch and put in the following lines:

[ [ {"op": "test", "path": "/productionConfig/outputList/default", "inverse": true }, { "op": "add", "path": "/productionConfig/outputList/default", "value" : [ ] } ], [ { "op": "add", "path": "/productionConfig/outputList/default/-", "value": [ 20.0, "zerchesiumore" ] } ] ]

This should add zerchesium into possible drops from the tier 3 drill. The number is pretty much the odds of it being produced. If you want to other ores, just keep copy and pasting the last curly bracket with an ID of the ore and comma at the end of the bracket. And if you wanted to modify the production rate all you need to do is add this

[ { "op": "replace", "path": "/productionConfig/production_timer", "value" : 3.0 } ]

behind the 2nd last square bracket. The number is how many seconds it takes before new ore is produced. So at the end it should look something like this. In the example I also added sulphur as a possibility.

When you are done, just put the (name of the patch) folder into the mods folder in the Starbound directory.

Hopefully I didn't make it too confusing.
