Would people prefer a special 'close' button, or a menu that offers a 'close' option as well as a choice of sideways/side-by-side orientation?

For the moment, if you'd like both versions to be installed simultaneously, follow these steps:

1. Install anunakin's x48 package.
2. Download the source tarball from my post yesterday.
3. Do the following as root:

Code:

tar xvfz x48-sideways-0.6.3.tar.gz
cd x48-sideways-0.6.3/debian/x48-sideways/usr/
mv bin/x48 /usr/bin/x48-sideways
mv share/applications/hildon/x48.desktop /usr/share/applications/hildon/x48-sideways.desktop
mv share/icons/hicolor/64x64/hildon/x48_icon.png /usr/share/icons/hicolor/64x64/hildon

4. As root, edit /usr/share/applications/hildon/x48-sideways.desktop and change "/usr/bin/x48" to "/usr/bin/x48-sideways". Change the "Name" field in this file to something meaningful, like "x48 (sideways)".
5. Also as root, execute the following commands:

Code:

update-desktop-database /usr/share/applications
gtk-update-icon-cache -f /usr/share/icons/hicolor
maemo-select-menu-location x48-sideways.desktop

The other files in the package are essentially the same as the normal-orientation versions, so there's no need to copy them.

BTW, instead of using one RESCALE_FACTOR for both x and y directions I can create different ones for x and y in order to fill the screen. Making the buttons bigger is easy, but getting all of the shadow effects right might not be; it might be better to try multi-color pixmaps (if that's possible). I'll look into it, but perhaps not right away.

/home/user/.hp48/rom

ElectricLungfish, are the shadow effects really required? The audible clicks from the key taps should be enough user feedback?

st5150: Thank you sir. I put the rom in there. It's not working its just crashing to desktop. Am I supposed to edit a config file to tell it the filename? Or what is the filename supposed to be? Mine is: HP48GXRomfile.bin

Mine is just called "rom" try renaming it.

I guess I'd just like it to look as good as that TI emulator...

You need a couple other files in /home/user/.hp48 as well; these are created by x48 during initialization.

Move the ROM file to your home directory. Assuming it is named HP48GXRomfile.bin (I obtained mine from hpcalc.org and it's named gxrom-r), execute the following command in the terminal (no need to be root):

Code:

x48 -rom HP48GXRomfile.bin -initialize

It will copy the ROM file to /home/user/.hp48/rom and create the other needed files there. You should see the prompt "Try to recover memory?", to which you should answer "NO".

More info is available in the README file contained in the source package (the .tar.gz file).

That's great to hear!

Let me know if I can help in any way.

I compiled v0.63 on an i386 box and experienced the same random shut off phenomenon while pressing keys as you described. I also tried to simplify a basic expression like x*x using fsimp from the attached fcalc library. It works fine on the i386 build, but hangs on maemo. I vaguely remember something about having to disable shared memory for the display to work properly on i386.

x48 0.6.3 has two skins, one for horizontal and other for vertical use, on horizontal you must use +netbook option...

I made some changes on x48 0.6.3 sources:

On emulate.c, same way like pinnchus made:

For binary compile and run without crash, you need remove libreadline5-dev or libreadline4-dev before run configure script.
