Changes in version 2.0.8.1
--------------------------
* some CPC emulation bugs have been fixed
Changes in version 2.0.8
------------------------
* 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 8) 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
