Current version: 1.10

FBZX is a Sinclair Spectrum emulator, designed to work at full screen using the FrameBuffer. Its main features are:

• emulates acurately the Original spectrum (both issue 2 and issue 3), the classic 128K, the Amstrad Plus 2 and the Amstrad Plus 2A. This include screen, keyboard and sound (both speaker and AY-3-8912 chip).
• Screen emulation is extremely acurate, so it can emulate border efects and even atribute efects.
• Supports Z80 snapshots, both loading and saving.
• Supports TAP (both read and write) and TZX (only read) tape files, supporting normal speed loading and fast speed loading.
• Emulates joysticks: kempston, cursor and sinclair.
• Emulates the Interface I and Microdrive.
• Is based in the great Z80 emulator created by Marat Fayzullin.
• Is distributed under GPL license (except the Z80 core, that can't be commercially distributed. See details in the homepage of Marat Fayzullin or in the documentation).

FBZX uses the SDL library, so you need it to run the emulator.
