- [CHG] En proves: fer un IN a un port no usat ara torna 0x00 en compte de 0xFF. Probablement hi haurà que revertir-ho.

- [NEW] Amb F9 es pot ficar o llevar un breakpoint en l'adreça on estiga el cursor del desensamblador.
- [NEW] Nou comando de la consola "show analyzer"
- [FIX] Quan es fa un full refresh mentres se debugga no ha de causar interrupcions. A més, ara mantenim els t_states i el punter a pantalla.
- [FIX] La instrucció CPIR llegia mal la memòria apuntada per HL al considerar si hi havia coincidencia
