At this time EmuZWin is one of the fastest and correct among other windowed emulators. It emulates Spectrum-128K/48K, TR-DOS (TRD, SCL, Hobeta), Interface-I Microdrive (MDR), supports most popular snap-formats (SNA, Z80), loading from the most popular tape formats (TAP, TZX, BLK), saving screenshots (SCR, BMP, PNG) and this list can be extended writing plugins. There is very convenient feature in the EmuZWin: reprogramming keyboard (it is possible to define which Spectrum keys are pressed by certain PC keys).
