This mod provides a table, data.sap, which is a mirror of what the data.raw would look like if space age was enabled.
You can deepcopy the prototypes and make changes, or simply data:extend{} the prototype directly.
Remember that some prototypes involve other prototypes, like items having a place_result for entities.

All graphics and sound paths have been pre-modified to use the graphics/sounds from the space age mod folder using relative filepaths, meaning this mod doesn't include any of the graphics/sounds themselves.
