Zero 0.7 Vanilla and Zero 0.6.5 now available!

Hola!

After months of grueling work, I’m proud to announce the Vanilla version of Zero, which is a regular Windows version of the emulator. I’ve tried to make it as good as I possibly could and hope some of you who wanted this version will enjoy it.

For those who still like the old look, there’s no need to fret because a new version 0.6.5 is also available! Both the versions can be downloaded from the Download page.

The combined change list is as follows:

  1. i’d suggest some features:
    – native gnu/linux support (essential nowadays, and this might improve portability to other operating systems)
    – ulaplus and sam-coupé palette emulation
    – trd and hard disk emulation
    – microdrive emulation
    – russian clones emulation (including atm-evolution (nedo conf) )

    1. Thanks for the suggestions:

      – Native gnu/linux support : A bit outside my area of expertise.

      – ULA Plus is already emulated. What is Sam Coupe palette emulation?

      – TRD is also already emulated. Hard disk emulation: Is there any practical use for this?

      – Microdrive emulation: Had considered it but I don’t know enough about the microdrive.

      – Russian Clones emulation: Pentagon is emulated.

  2. Hola querido Spectrum-maníaco!

    Estoy tratando de bajar tu emulador, pero me da fallo al descomprimir.
    Estaría bueno que le dejaras la opción de poder cargar otras rom (bios) de clones de zx.
    en mi pais fue muy popular un clon brasilero: TK-90X y TK-95, ambos clones son un tanto incompatibles, pero con un equipo de amigos, alla por los años 86 en adelante, convertimos un importante número de juegos y utilitarios para estos clones.
    Gracias por tu esfuerzo, y si te puedo ayudar en algo estoy a tus órdenes.

    1. Hi Juan,

      Thanks for writing in. I believe you want me to add TK-90x support to the emulator. Currently, I don’t have plans for this as I’m taking a break from writing the emulation engine. But that’s why I made the project open source, so that anyone can add to it if they desire! I may come back to it in the near future, but I won’t make any promises. 🙂
