WHAT EMULATES RIGHT IN FBZX WII?

-Screen timmings in 48K and 128K mode.
-Screen generation, so border efects and even attribute changing efects
    should work fine.
-48K sound (included the low-pass filter efect of Tape out).
-128K sound (fully emulation of the AY-3-8912).
-Trash in the bus when reading from a non-existing port. This is right generated
    (from the data being displayed in that moment) so games works right (like
    SHORTCIRCUIT, that runs without flickering).
-Spectrum 48K Issue 2 and 3 efects in the EAR bit are correctly emulated.
-Priority of joystick over keyboard.
-Snow efect when I register points between 64 and 127.
-Emulation of Interface I and Microdrive (only one drive).
-Memory contention
-Emulates Spanish 128K from Investronica/Sinclair, the Amstrad Plus 2, the Amstrad Plus 2A and NTSC 48k
-Allows to insert POKE values an files in memory (inmunity, infinite lives...)
-Can load and save SCR snapshots
-ULAPlus support
-Z80 snapshots, both loading and saving, and loading SNA snapshots. 
-TAP (both read and write) and TZX (only read) tape files, supporting 
-Fast loading and instant speed loading
-ZIP archive files 
-Tape browser
-FTP client for loading games from internet repositories (e.g. WOS).
