hUGEDriver and hUGETracker
==========================

Repository: https://github.com/SuperDisk/hUGEDriver
Upstream README (`Quick start (GBDK)` + `License` sections) bundled as
`hUGEDriver.upstream.asm` (the canonical RGBDS implementation, ~1900 lines).

From the upstream README:

> ## License
>
> hUGETracker and hUGEDriver are dedicated to the public domain.

That is, hUGEDriver carries no encumbrance — distributed under CC0 / public
domain dedication. We therefore include both:

  - hUGEDriver.upstream.asm     The full RGBDS source-of-truth (CC0).
  - hUGEDriver.{c,h}            A compact SDCC-native rewrite providing the
                                hUGE_init / hUGE_dosound / hUGE_mute_channel
                                surface against a simplified song format,
                                authored from scratch for romdev.

The compact rewrite is independently CC0-dedicated for the same reason —
no upstream code is copied; it implements a documented public-domain
interface against the public GB APU register set.
