The latest core doesn't support esxdos, so i decided to play only tap format games. Since some are only in .z80 format i used Z802TZX to convert them in TZX and then, through TZX2WAV, in CSW format. The sintax is:
> TZX2WAV -c1 Game.tzx Game.csw
the csw files play well but at the end of loading dont' start. Converted tzx files work well on Spectaculator emulator.
