Speccy 1.9

Description

Speccy emulates 16kB, 48kB, and 128kB versions of Sinclair ZX Spectrum, as well as Spectrum +2, +2A, and +3, as well as Timex Sinclair models. Although I had done some ZX-related work in the past and even maintained comp.sys.sinclair FAQ at some point, for many years I abstained from writing a Sinclair ZX Spectrum emulator. It was mostly due to the fact that there are so many other Spectrum emulators around, so writing another one seemed redundant. On the other hand, the lack of a Speccy emulator felt like a gaping hole on my resume :). So, here it is, yet another Spectrum emulator, trivially named Speccy. Currently, Speccy is not a commercial project but rather a test bed to try out different things before introducing them into my other emulators. Thus, feel free to use it as you wish (as long as it is not commercial). If you find a bug, have an idea on the further Speccy development, or would like to port Speccy to a new platform, please, let me know.

At the moment, Speccy supports all types of ZX Spectrum joysticks and the Kempston mouse. The AMX mouse support is not yet complete. Both ZX printer and the Timex (aka Alphacom 32) printer are supported and will print to a file using ASCII "graphics". AY8910 PSG chip is obviously supported, in both 128k and Fuller modes. Only BetaDisk/TR-DOS disk interface is currently supported, although other disk, wafer, or microdrive devices appear on the menu. These are being worked on.

Speccy will load files in .Z80, .SNA, .TAP, .TZX, .FDI, .TRD, and .SCL formats. It will also load screenshots in the .SCR format. You may save files in .Z80, .SNA, .FDI, .TRD, .SCL, and .SCR formats. Please notice that F4 starts/stops tape while F5 invokes the platform-independent configuration menu. Some options on this menu are not available from Windows menus. Use ALT+ENTER to switch between windowed and full screen modes. ALT+PGUP increases audio volume while ALT+PGDOWN decreases it. Finally, pressing PGUP will fast forward the emulation to skip over lengthy operations like tape loaders.

Speccy has an interesting feature of automatically converting ZX beeper sounds into MIDI score and storing the soundtrack to a log for later playback. Choose "Audio | Convert Wave To Melody" and then "Audio | Log Melodic Sound" menu options to enable this feature.
