As every other piece of software I know of, @code{saturn} is not
|
||
|
|
bug-free. This chapter lists known bugs and gives some tips and tricks
|
||
|
|
that, I hope, will be useful to circumvent the most common problems.

ROM views are not reset when @code{-reset} is given on the command line;
|
||
|
|
as a result, @code{-reset} could be unable to recover from all possible
|
||
|
|
calculator hangup conditions. This bug affects the HP49 / HP40 models
|
||
|
|
only. As a workaround, remove the @code{cpu} and @code{mod} state files
|
||
|
|
and restart the emulator, with @code{-reset}.
|
||
|
|
|
||
|
|
@item
|
||
|
|
The peripheral module initialization sequence can generate an interrupt
|
||
|
|
request to the CPU emulator; this can give a segmentation fault if the
|
||
|
|
CPU state loaded from file was corrupt. This situation cannot be
|
||
|
|
recovered with @code{-reset}, because the CPU reset is executed much
|
||
|
|
later in the emulator's init sequence. This bug bites only if something
|
||
|
|
terrible happened to your CPU state file, or if you attempted to load a
|
||
|
|
state file saved on a different host architecture; in this case, remove
|
||
|
|
the @code{cpu} state file and restart the emulator, with @code{-reset}.
|
||

The serial port emulation no longer works when the machine state
|
||
|
|
is saved and then restored while the serial port was @strong{on};
|
||
|
|
the port is automagically turned @strong{off} when the state is restored,
|
||
|
|
but nobody cares to notify the calculator's firmware about this.
|
||
|
|
|
||
|
|
@item
|
||
|
|
Some X keysyms, for example @code{Return} and @code{Tab}, don't work
|
||
|
|
correctly in keyboard shortcuts, because Motif insists on grabbing
|
||
|
|
them for its own use.

The emulation of the LCD display is poor; in particular, neither
|
||
|
|
gray-scale nor hardware-assisted scrolling are supported.
|
||
|
|
As a result, most action games will not work on @code{saturn}.
|
||
|
|
|
||
|
|
@item
|
||
|
|
The emulation of the Flash ROM is limited to the bare minimum
|
||
|
|
needed to run the HP49 firmware.
|
||
|
|
|
||
|
|
@item
|
||
|
|
The infrared port is not emulated at all.
|
||
|
|
|
||
|
|
@item
|
||
|
|
There is no support to revector the calculator's serial port
|
||
|
|
to a real serial port on the host machine. Only pseudo-terminals
|
||
|
|
are supported.
