@@ -12,9 +12,20 @@ Un motore isometrico sperimentale per Game Boy (DMG/CGB) scritto in C con **GBDK
* **Delayed Auto Shift (DAS)**: Controlli reattivi e confortevoli con delay iniziale di 12 frame e ripetizione ogni 6 frame per il movimento continuo tenendo premuto il D-Pad.
* **Autotiling Intelligente**: Calcolo dei vicini (maschera a 4 bit) per selezionare automaticamente il bordo e gli angoli di ciascuna tessera del pavimento (16 varianti per ognuno dei 2 stili di pavimento alternati a scacchiera).
* **Pipeline di Asset Ottimizzata**: Generazione procedurale di tile e sprite da script Python (`generate_assets.py`) e compilazione in C tramite `png2asset`.
* **Test Headless & Computer Vision**:
* Simulazione dell'input e verifica dello stato direttamente leggendo i registri WRAM del Game Boy in esecuzione.
* Rilevamento di glitch grafici (pixel neri o spazi vuoti non allineati) sulla ROM renderizzata usando filtri morfologici di **OpenCV**.
- Animazione completa dei movimenti del giocatore.
- Transizione al Game Over alla collisione.
- Menu Iniziale con copertina d'arte a 2-bit nativa per hardware Game Boy.
### Soundtrack
Il gioco implementa la musica generata proceduralmente manipolando i registri audio hardware del Game Boy in `engine.c`.
1. **Title Theme:** Una solenne e misteriosa melodia composta da 32 battute basata sugli accordi La minore, Sol, Fa e Mi, che accompagna la schermata d'avvio a schermo intero.
2. **Gameplay Theme:** Un battito ritmico ansioso che accelera progressivamente l'intensità all'inseguimento del fantasma, aumentando la pressione psicologica sul giocatore.
3. **Game Over Theme:** Un concerto tragico polifonico di 128 note con percussioni sinfoniche, basso virtuoso e drammatica discesa melodica, per sottolineare la sconfitta del giocatore.
## Compilazione
Assicurati di aver installato [GBDK-2020](https://github.com/gbdk-2020/gbdk-2020).
