Appendix I

Optional Extras

The 13 groups of dependency that a plain install leaves out, what each one unlocks, the module c64cast --doctor imports to tell you it is there, and the packages it brings with it.

The Extras#

Extras do not accumulate. Installing c64cast[midi] over c64cast[video] leaves you with MIDI and no video, so the install worth asking for is c64cast[all] — or uv sync --all-extras from a checkout. c64cast --doctor says which of these are importable and which are missing.
