# Tonic Tumble: credits and third-party notices

Tonic Tumble is an original game built on the **AngheloAlf/drmario64 decomp**
(https://github.com/AngheloAlf/drmario64, MIT License, Copyright (c) 2023 AngheloAlf). The program in
`tonictumble.z64` is compiled from that decompilation (including its decompiled libultra). Every picture,
tune, sound, 3D shape and line of text was generated for this project; no data from the original game ships.
Source of the clean-room pipeline: https://github.com/andrewnakas/drmario64-cleanroom (MIT License).

The ROM boots with an original IPL3 stub (CC0) and carries small tagged RSP microcode placeholders
(CRUCODE1, CC0) instead of microcode, so it runs only in the patched emulator core bundled here (not on
real hardware or low-level emulators).
