Current version: 2.10.0

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

• emulates acurately the Original spectrum (both issue 2 and issue 3), the classic 128K, the Amstrad Plus 2, the Amstrad Plus 2A and the Spanish 128K. 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, and loading .SNA snapshots.
• 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.
• Emulates the ULAPlus
• Based in a new, fully free, Z80 emulator (Z80Free).
• Is distributed under GPLv3 license.

FBZX uses the SDL libpulse0 and libasound2 libraries, so you need them to be able to run the emulator (unless you recompile it; in that case you can choose which of them to use).
