Introduction :

FBZX is a ZX Spectrum emulator for FrameBuffer written by Sergio Costas (http://www.rastersoft.com/fbzx.html) and ported to Wii by Oibaf.
FBZX Wii can be found on google code at fbzx-wii.googlecode.com
The port uses SDL Wii.

The main features are:

Emulates accurately the Original 48Kspectrum (both issue 2 and issue 3), the classic 128K, the Amstrad Plus 2, the Amstrad Plus 2A and the Spanish 128K. This includes screen, keyboard and sound (both speaker and AY-3-8912 chip).
Screen emulation is extremely accurate, so it can emulate border effects and even attribute effects.
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 up to 2 joysticks of types: kempston, cursor and sinclair1 and sinclair2.
All the wiimote, nunchuck and classic controller buttons and joypads are fully configurable.
Virtual keyboard support.
Emulates the Interface I and Microdrive.
Emulates the ULAPlus
Based in a new, fully free, Z80 emulator (Z80Free).

Version 4

In Joypad mode, the nunchuck works now
New code for Y-3-8912 emulation
Fixed RETN and RETI Z80 instructions
Fixed Flag emulation for many Z80 opcodes: Speedlock loader works now. Only the Flag in Bit n, (HL) is not correctly emulated.
