Uno de los emuladores más conocidos dentro de la escena del ZX Spectrum es el de Jonathan Needle. En estas fechas acaba de aparecer la que es la última versión del Spectaculator y éstas son las implementaciones realizadas, copipasteadas de la web del autor:
· Spectrum +3 disk images in IPF format are now supported. You will need to install the IPF Support Library before IPF disk images can be used.
· The display renderer has been completely rewritten to work better with modern graphics cards and later versions of Windows. A minimum version of DirectX 9 with a graphics card capable of hardware-accelerated · · · Direct3D is required. This fixes the problem of blocky graphics on ATI and nVidia cards on Windows Vista and Windows 7.
· Added Shay Green's NTSC Libraries to provide a more TV-like display. You can choose from the simulation of a fairly high-quality RGB display right down to a noisy RF (a.k.a. aerial) connection.
· Implemented correct beeper emulation with respect to the four voltage levels produced by the ULA. The correct sound is now heard from (the few) programs using both the EAR and MIC bits to drive the speaker.
· Fixed emulation of the unconnected upper AY registers.
· Fixed reading AY control port using port $bffd on the +2A and +3 only (thanks Woody).
· Added 4x zoom mode.
El programa (shareware, por cierto) se descarga desde la web oficial
LINK y se instala encima de la anterior versión (v7.00).
