Changes in version 1.2.5:
* implemented Lua scripting in the debugger; this makes it possible to write complex rules for breakpoints, but can have other uses as well, since the script can read and write memory and CPU registers, in addition to having access to the standard Lua library functions
* changed the debugger window layout so that there is a larger window with only two tabs
* the disassembly view in the debugger now allows for paging backward, and the disassembly and memory dump displays can also be scrolled with the mouse wheel
* made the serial bus delay for the 1541 high timing accuracy mode adjustable; while the default setting works with all the disk turbos tested so far, this option may be useful for debugging purposes
* when using audio files as tape images, the signal read or written can optionally be inverted for compatibility with other software
* the enabling of 6551 ACIA emulation is now configurable, rather than being fixed to machine configurations with 64K or more RAM
* SID emulation and floppy drives with no disk image attached can be disabled from the
GUI menu to reduce CPU usage; previously, these automatically enabled features could only be turned off by a forced or hard reset
* added new
GUI menu items for resetting floppy drives
* new command line option (-tape) for loading tape images on startup; it has also been made possible to automatically load a file with .prg, .p00, .d64, .d81, or .tap extension by using the file name as a single command line argument
* minor bug fixes and optimizations
