alexandClaude Sonnet 5 168d6a71bd Fix esp32 wait-timing race, rename wc_api.lib, keyboard: Enter-to-advance 
esp32.c: two-phase esp_wait_busy() so a stale non-BUSY status right after
esp_cmd() isn't mistaken for completion (fixed a real TRACK_PLAY/0x88 race
on heavier XM files); added single-phase esp_wait_not_busy() for
esp_send_dma()'s per-chunk wait, which never actually sets BUSY and was
timing out on every chunk under the two-phase version.

vgm_wc_api.lib renamed to wc_api.lib (build.bat updated to match).

Keyboard: tried replacing wc_key_esc/pgup/pgdn/space with a raw PS/2-FIFO
reader (matching how VGMPLAY.WMF's own player reads keys) so Enter could
also advance to the next file. Reverted after two confirmed hardware
regressions (esp32 transfers failing with ESP_ERR_INV_XM, and the keyboard
going unresponsive once WC's own PS/2 scanning was disabled to stop it
competing with the raw reads) - VGMPLAY's approach relies on a full custom
interrupt handler xmplay has no equivalent need for. Back to the simple
wc_key_*() wrappers, plus wc_key_enter() so Enter now advances too, and
wc_key_wait_release() (called after wc_gedpl()) to debounce the Enter/F3
that launched the plugin itself.

Also: About window now centers dynamically for all three WC text modes
(90x36/80x25/80x30) instead of a fixed position, and matches the main
window's color scheme.

alexandClaude Sonnet 5 ecf52d60c8 docs: README + ВНИМАНИЕ - конфликт со стандартным ftview по .XM/.XMZ 
Стандартный ftview сам регистрируется на .XM/.XMZ - те же расширения,
что и xmplay. Таблица "расширение -> плагин" в WC статическая, так что
при совместной установке они конфликтуют. Нужно использовать
переработанную версию ftview (расширения убраны):

alexandClaude Sonnet 5 ee64fb85a9 Fix esp32 detection, add colored caption, live stats, single-loop playback 
- Fix state_esp init bug: crt0.s never runs GSINIT and hex2bin fills
  unbacked memory with 0xFF (not 0), so a plain zero-init global always
  read 0xFF on load; give it a real 0xFF sentinel initializer instead.
- Vendor demyanenko-d/VGMPLAY.WMF's wc_api library (SDCC 4.6.0 +
  --sdcccall 1) instead of hand-rolled PRSRW/PRIAT wrappers, which
  corrupted esp32 file loading in three different shapes; colored "File:"
  caption now works.
- Trim shared-file footprint: vendor only the esp32.c functions actually
  used, drop unused sdklib.h/sdk.lib linkage.
- Re-enable periodic live stats (Pattern/Row/BPM/Time/progress bar).
- Limit playback to one loop via TRACK_SET_PARAMS/MAX_LOOP_COUNT, and
  auto-advance to the next file when a track finishes on its own
  (detected via a PLAYING->STOPPED ESP_REG_TRACK_STATUS transition).
- Pin the Z80 clock to 14MHz for the whole plugin lifetime so esp32 SPI
  wait-loop timeouts (raw iteration counts, not real time) don't depend
  on whatever turbo setting was active before the plugin started.
- Pad TRACK_INIT's timeout well past the firmware's 5s song-length
  measurement cap (XM_MEASURE_MAX_US).

# XM Player
Плагин для Wild Commander (ZX Evolution / TS-Conf), проигрывающий XM, XMZ
(запакованный gzip'ом XM) и S3M модули через ESP32-сопроцессор платы. Z80
только передаёт файл на ESP32 и отображает окно со статусом; сам разбор
модуля и синтез звука выполняет прошивка ESP32.
> ⚠️ **Несовместим со стандартным ftview.** Оригинальный (стандартный)
> плагин `ftview` сам регистрируется на расширения `.XM` и `.XMZ` — ровно
> те же, что и у этого плагина. У Wild Commander таблица "расширение →
> плагин" статическая, зашита в заголовок при сборке, и если файл поставить
> вместе со стандартным `ftview`, они будут конфликтовать за одни и те же
> расширения. Используйте переработанную версию `ftview` (расширения `.XM`
> и `.XMZ` из неё убраны, воспроизведение вынесено в этот плагин) —
> она лежит отдельным репозиторием: https://git.alexkorochinskiy.ru/alex/ftview.git
## Требования
- ZX Evolution / TS-Conf с прошитым ESP32-сопроцессором
- Wild Commander (заголовок плагина версии 10+, есть в текущих сборках)
- переработанная версия `ftview` (см. предупреждение выше), а не стандартная
## Возможности
- Проигрывание `.XM`, `.XMZ`, `.S3M`
- Окно с живым статусом: имя файла, статус загрузки/воспроизведения,
паттерн, строка, BPM, прошедшее/общее время, прогресс-бар
- Ошибки выводятся прямо в строке статуса (с кодом ошибки ESP32, например
`Playback error (0x90)`), без отдельного всплывающего окна
- Автоматический переход к следующему файлу по окончании трека
- Параметр `stoponerror` в ini — остановка на ошибке вместо автоперехода,
удобно, чтобы найти, какой именно файл в подборке вызывает проблему
## Управление
| Клавиша | Действие |
|--------------|----------------------------------------------|
| PgDn, Enter | Следующий файл |
| PgUp | Предыдущий файл |
| Esc | Остановить воспроизведение и выйти |
| Space | Выйти, не останавливая текущее воспроизведение |
## Установка
Скопировать `xmplay.wmf` в каталог плагинов Wild Commander. Плагин сам
регистрируется на расширения `.XM`, `.XMZ` и `.S3M`.
Чтобы при ошибке воспроизведения плагин останавливался, а не переходил
сразу к следующему файлу, добавить в `wc.ini`:
```
XMPLAY.WMF -stoponerror=1
```
(`0` или отсутствие параметра — поведение по умолчанию: автопереход при ошибке.)
## Сборка
Нужен [SDCC](http://sdcc.sourceforge.net/) версии 4.6.0 (зафиксирована в
`build.bat`) и `hex2bin` — оба есть в тулчейне SDK ZX Evolution.
```
build.bat
```
Результат — `xmplay.wmf` в корне проекта.
## Благодарности
Собран на основе `wc_api.lib` из `demyanenko-d/VGMPLAY.WMF` — используется
для доступа к API Wild Commander (окна, вывод текста, клавиатура, ini-параметры).
## Статус
Проверено на реальном железе: воспроизведение, живая статистика,
прогресс-бар, обработка ошибок и управление с клавиатуры.
