26/09/15 - DSP Emulator 0.16 WIP Uploaded

Amstrad CPC 464,664 & 6128
- ROMS - By default the files are:
-CPC-464: 'CPC464.ZIP' --> 'cpc464.rom' CRC: 0x40852F25
-CPC-664: 'CPC664.ZIP' --> 'cpc664.rom' CRC: 0x9AB5A036 and 'amsdos.rom' CRC: 0x1FE22ECD
-CPC-6128: 'CPC6128.ZIP' --> 'cpc6128.rom' CRC: 0x9E827FE1 and 'amsdos.rom' CRC: 0x1FE22ECD
- Keyboard: Mapped the keys for each of the CPC. To press the '|' press left shift key and '><' next to the Z.
Emulation of pressing keys 'F1' to 'F10' you must press right Shift at the same time.
- Joystick: Emulated with the redefinable keys or external joystick.
- Virtual Tape: you can load ZIP, CDT, WAV and CSW. Are working the classical loading squemes (bleepload, alkatraz, SpeedLock ...). Use the mouse to move inside the virtual tape and select the starting position.
- Sound: All version have the AY-8912 chip
- Floppy disk: Emulated the functions of the NEC-765, just missing writing functions. Supports the format 'DSK' and the 'extended' DSK formats.
- Snapshots: Support load/save 'SNA' format
- To do
- Some disk protections are not working (a few left)
- Some video effect are missing (M6845 chip)
