What's new in ep128emu 2.0.9.1
Jan 4, 2011
- some debugger changes related to ignore breakpoints
- it is possible to delete single breakpoints in Lua scripts by using a negative priority value
- minor 6845 CRTC emulation bug fix
- fixed bugs in closing the debugger window with the Esc key
New in ep128emu 2.0.8.1 (May 11, 2010)
- Some CPC emulation bugs have been fixed
New in ep128emu 2.0.8 (Jan 26, 2010)
- 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
New in ep128emu 2.0.6 (Dec 14, 2008)
- Various improvements have been made to the debugger and the installer.
- FILE: is now the default device on startup when using the epfileio.rom extension. Floppy drive emulation improvements.
- In the memory configuration, ROM files can also be loaded to segments 40h to 43h.
- Video display improvements and bugfixes.
- Some NICK emulation fixes.
- Screenshots are saved in BMP format now, instead of TGA.
- Various user interface improvements.
- A new 'Gtk+' GUI theme.
- A number of minor bugs have been fixed.
