This folder contains the image binaries for the NES version of Elite. They have been extracted from the game binaries on Ian Bell's personal website, and unpacked into binary files (which is what the game works with) and PNGs (which are viewable for humans). They are not currently used in the build process.
The original packed data can be found in the source at the label of the same name as each extracted image (e.g. faceImage0, headImage0, systemImage0, fontImage and so on).
The unpack-data.py and combine-images.py scripts can be found in the 2-build-files folder.
Right on, Commanders!
