ep128emu v2.0.8 release
Posted January 24th, 2010 by IstvanV

* implemented ZX Spectrum 48/128 and Amstrad CPC emulation; for now, only a basic configuration of these machines is supported (there is no disk emulation yet), although the emulation accuracy should be good. See the README file for more details
* new command line options for selecting the machine type to be emulated: -ep128, -zx, and -cpc
* undocumented Z80 flags are emulated more accurately - the only instruction that is still not correct is ´BIT n, (HL)´
* fixed bug in the emulation of DAVE port B6H, which prevented some games from working
* reduced the time before the floppy write buffer is flushed from 4 seconds to 1 second
* the editor buffer in the monitor has been increased from 120 to 160 lines
* the monitor TR (trace) command has a new optional parameter now that controls the printing of additional information about the video position and Z80 registers
* new Lua functions: readWord(), readWordRaw(), writeWord(), writeWordRaw(), getIFF1(), getIFF2(), setIFF1(), setIFF2(), getVideoPosition(), and getRawAddress(); these are documented in the README file
* detailed information about Lua errors is now also printed if the error occurs in an extension function implemented by the emulator
* segment:offset style breakpoints allow the offset to be greater than 3FFFH (the two most significant bits are ignored, but must match when specifying an address range)
* the Z80 disassembler in the debugger now supports more undocumented instructions
* fixed bug in the Lua example script
* the file I/O extension ROM (epfileio.rom) has been modified so that EXOS block read and write (6 and calls are implemented in Z80 code, and not in the emulator; this reduces the speed of these operations to a level similar to disk drives, and allows watchpoints set on the read or written memory area to work
* the source code of epfileio.rom is included
