ZX-Poly Emulator review
A focused open-source emulator for ZX-Poly modes, enhanced video, and varied media formats.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ZX-Poly Emulator is an open-source Java emulator and proof-of-concept platform for users exploring ZX-Poly multi-CPU emulation and ZX-Spectrum 128 software. It runs either in ZX-Poly mode, using synchronized Z80 CPUs, or in standard ZX-Spectrum 128 mode. Pre-built downloads support Windows, macOS, and Linux, while a cross-platform JAR provides another way to run the emulator.
Its strongest area is media and video support. The emulator loads Z80, SNA, SZX, ZXP, ZIP, ROM, and PROM images, along with TZX, TAP, and WAV tape files. It supports WAV export for TZX and TAP, plus TRD and SCL disk images. Video output includes standard 256x192 and enhanced ZX-Poly modes, while gamepad and joystick support helps accommodate interactive software. These capabilities make it a practical choice for format-heavy experimentation and for examining the enhanced video behavior that distinguishes ZX-Poly from a standard ZX-Spectrum 128 setup.
The trade-off is focus. ZX-Poly Emulator is centered on 128k support and a specialized multi-CPU concept rather than broad coverage across ZX Spectrum models. Spec256 emulation is also restricted, so users seeking a wider or more complete implementation of that area may need an alternative. Choose it for open-source desktop emulation, varied image and tape handling, controller support, and ZX-Poly video experiments; choose something else if broader model coverage or a less experimental scope matters more.
ZX-Poly Emulator pros and cons
- Where it wins
- Multi-CPU ZX-Poly emulation with synchronized Z80 CPUs
- Broad snapshot, tape, disk, ROM, and PROM image support
- Windows, macOS, Linux, gamepad, and joystick support
- Where it doesn't
- Focused on 128k support rather than broader ZX Spectrum coverage
- Spec256 emulation is restricted
- Proof-of-concept focus may not suit production-oriented use
