It's available on Windows, by writing a DLL and placing it in a directory named 'Extensions' inside the directory where QemuLator.exe is.

Re: IO.FLINE doubts and emulation

Depends on where you intercept the call (LBYTES, TRAP#3, device driver I/O routine, or some other place)... If you intercept at the TRAP or device driver I/O routine, A1 should be a valid RAM address. If not, you may have a bug somewhere else.

Re: QL MODE 8 Flash Bit

In the on state, the flash bit acts as a toggle: when the flash bit is encountered, that pixel color is also used for the following pixels, until either there is another flash bit set or the end of the scan line. ...
