release: bump gc to v0.2.0; update pce CHANGELOG for v0.1.0

gc: cut a new release under the short-codename convention. v0.2.0
captures the subdir rename (gamecube/ -> gc/) and the GBA-disconnect
GCN ghost-detect fix. Historical gamecube-v0.1.0 stays as a frozen
snapshot.

pce: rewrite the v0.1.0 changelog body to reflect what actually ships
(title bar + sprite-based bouncing logo screensaver matching gc/gba),
not just the upstream PCE_Mouse_Test faithful port that was sketched
out before the screensaver work landed. VERSION stays 0.1.0.

gba: no changes; ships as-is at v0.1.0.

 # Joypad Tester — GameCube — Changelog
 
+## v0.2.0 — 2026-05-11
+
+First release under the new short-codename convention. The subdir is
+now `gc/` (was `gamecube/`) and the release tag is `gc-v0.2.0` (was
+`gamecube-v0.1.0`). The historical `gamecube-v0.1.0` tag/release stays
+intact as a frozen snapshot of the old layout — future releases all
+use the `gc-` prefix.
+
+### Fixed
+
+- GBA disconnect no longer ghost-detects as a regular GameCube
+  controller. libogc's `SI_GetType` walks through transient values
+  during cable removal that mask to `SI_TYPE_GC` (with or without
+  `SI_GC_STANDARD` set); the bare type-match fallback was latching
+  those as "GCN". Added a `gc_chan[]` sticky cache parallel to
+  `kbd_chan` / `wheel_chan`, gated on `SI_GC_STANDARD` + no
+  `NO_RESPONSE`, so transient reads can't flip the port label.
+
+### Changed
+
+- Subdir rename `gamecube/` -> `gc/` to match the short-codename
+  convention used by `gba/`, `pce/`, and future consoles. Tag prefix
+  shifts from `gamecube-v*` to `gc-v*`. `TARGET_CONSOLE=gamecube|wii`
+  inside the libogc build is unchanged (that's the libogc internal
+  platform name, not our subdir codename).

 ## v0.1.0 — 2026-05-11
 
-Initial release. Faithful port of dshadoff's `PCE_Mouse_Test` baseline
-as a joypad-tester subdir.
-
-- Detects 2-button / 6-button PC Engine pads via `joy(0..4)` and
-  reports raw bit patterns for all five potential controller slots
-  (single pad on port 0, or up to five pads through a multitap).
-- Detects the PC Engine mouse, reports `mouse_x() / mouse_y()` per-frame
-  deltas, and accumulates them into absolute X / Y coordinates.
-- **I** button (or right mouse button) toggles between mouse-enabled
-  mode (decoded mouse state) and raw controller mode (raw joybus
-  reads).
+Initial release. Builds on dshadoff's `PCE_Mouse_Test` baseline,
+extended with a labelled main screen and an idle screensaver matching
+the GameCube and GBA testers in this repo.
+
+### Main screen
+
+- Yellow title bar ("Joypad Tester - PC Engine") rendered on its own
+  BG palette so it stays distinct from the live data.
+- White P1..P5 + Mouse readouts in a two-column layout. P1..P5 cover
+  the five potential PCE controller slots (single pad on port 0, or
+  up to five pads through a multitap).
+- Mouse section reports `mouse_exists()`, per-frame `mouse_x()` /
+  `mouse_y()` deltas, and an accumulated absolute X / Y.
+- Cyan footer: "Press I button or right-click to toggle mouse mode."
+  Same toggle behaviour as upstream PCE_Mouse_Test.
+
+### Idle screensaver
+
+- After 30 seconds of inactivity, the screen clears and the 64×64
+  joypad logo bitmap bounces across the display, color-cycling
+  through red → green → yellow → blue → magenta → cyan → white on
+  each wall bounce. Same artwork, palette, and motion cadence as
+  the GameCube and GBA testers.
+- Logo is rendered via four 32×32 hardware sprites in a 2×2 grid
+  (PCE 4bpp planar format). Sprite data is generated by
+  `buildtools/make_logo.py` from `pce/branding/logo_64.png` (a
+  hand-editable 64×64 1-bit PNG), or — when no hand-edit exists —
+  rasterised at 64×64 from `joypad/branding/logo_solid.svg` via
+  `rsvg-convert`.
+- Any input wakes the screensaver and restores the main display.
+
+### Build / toolchain
+
 - Builds to `joypad-tester.pce` via a Docker image we maintain
   (`pce/buildtools/Dockerfile`, HuC pinned to `uli/huc@52a556a`).
-- Source file: `pce/src/joypad_tester.c`. Includes upstream MIT
-  copyright header.
+- Source: `pce/src/joypad_tester.c`. Upstream MIT copyright header
+  preserved.
+- HuC tokenizer gotchas documented in the source header:
+  comments must be pure ASCII (no em-dashes / curly quotes), and
+  initialiser trailing commas are not accepted.
 
 ### Known limitations
 
-- No on-screen button labels yet — bits are shown as raw hex. The
-  GameCube tester's per-port live readout style will land in a follow-
-  up.
-- No accessory detection / rumble (PCE has no equivalent on the joybus).
+- No per-port button labels yet — joy state is still a raw 16-bit
+  hex bit pattern (matching upstream). A labelled per-port readout
+  in the style of the GameCube tester is planned for v0.2.0.
+- No accessory detection or rumble (PCE has no equivalent on the
+  joypad protocol).
