Zedex review
A feature-rich free Android emulator for gaming, media capture and library browsing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Zedex is a free, open-source ZX Spectrum emulator for Android 11 and later. It supports Sinclair, Timex, Pentagon, Scorpion and Spectrum SE machines, including 48k, 128k, plus2 and plus3 models. The app is aimed at Android users who want more than basic game loading: it combines emulation with touch controls, gamepad support, visual effects, recording and a built-in game library. It is distributed through the project's GitHub repository as GPL-licensed software.
Its strongest area is breadth. Zedex supports TAP and TZX tape formats, SZX, Z80 and SNA snapshots, plus disk, cartridge, microdrive and RZX files. Save states, built-in cheats and custom memory pokes cover common convenience features, while scanline, CRT, RGB, composite and RF effects provide several display options. Touch joysticks, virtual keyboards, Kempston mouse emulation, remappable controls and hotkeys make it adaptable to different games and hardware. PNG screenshots and GIF or MP4 recording add a clear media-focused layer, while metadata scraping and online catalog browsing help organize a library.
Zedex is a strong fit for Android gaming, especially for users who value controller flexibility, visual customization and capture tools alongside emulation. Peripheral support includes DivMMC with esxDOS, tape deck support, game controllers, +3 floppy drives and beta 128/TR-DOS support. Its focus is narrower than desktop-oriented alternatives: Android 11 or later is the supported host platform, and there is no debugger. Users who need desktop coverage or debugging tools should choose an emulator designed around those requirements instead.
