Gui.data

Determines which machines appear in which menus on the production screen.

Example:

{       "basic":["dissolver","evaporator","ioniser","agglomerator","autoclave","cooler"], "advanced":["chromatograph","uv_curer","sequencer","hadron"], "auxiliary":["fixed_belt","incinerator","multimixer","shaker","packer","centrifuge"], "makers":["pill_maker","cream_maker","sachet_maker","syringe_maker"] }

The names here have to match the names of equipment in the equipment.data file. You can add additional machines to the equipment.data file, include them in one of the lists in gui.data and this will allow you to access that machine via the menu.

By default these machines will be locked. You can make them unlockable by adding a research project to research.data or add them to the starting research field in scenarios.data.
