- Afegim el tap i el savestate de Alien 8 per a provar

- Provant el berserk mode
- Medint els t-states de altra forma
- iff1, iff2 i im afegits al array de registres de la cpu
- [NEW] getRegs() del modul z80
- [NEW] loadstate() i savestate() al modul z80debug
- [NEW] "load arxiu" i "save arxiu" en consola per a carregar i guardar savestates
- [ONGOING] "tape load arxiu" i "tape play" per a canviar de cinta i playarla
- Buffer de audio més gran. Ara el buffer es circular. Continuem intentant desfer-se del jittering
