"""
|
|
Genera file .mem con encoding tier+ASCII per modulo pause_text.
|
|
|
|
Formato output: 1 word 9-bit per char (2 bit tier + 7 bit ASCII), salvato
|
|
come 16-bit hex (1 word per riga, valore <= 0x1FF).
|
|
|
|
Sintassi sorgente .txt:
|
|
- Righe che iniziano con `@` sono separatori/commenti — IGNORATE.
|
|
- Righe che iniziano con `N:` (N=0..3) → tier=N, testo dopo i due punti.
|
|
- Righe normali → tier=0 (default, bianco).
|
|
- Righe vuote → riga vuota tier=0.
|
|
|
|
Char accettati: 0x20-0x5F (uppercase). Lowercase a..z viene convertito in A..Z.
|
|
Char fuori range diventano space (0x20).
|
|
|
|
Usage:
|
|
