PANDORA.XU4
This project builds the PND file for the XU4 Ultima IV Recreation project. The PND file can be used on the OpenPandora.
XU4 needs the MS-DOS binaries of the original Ultima IV by Origin. For legal reasons, the original game data is not included in this PND, but, as Ultima IV is legally optainable, it downloads the data on the first start.
Build the PND file
You will need mksquashfs. Install it using the package manager of your choice.
./build.sh
This will create the pandora.xu4.thred.pnd file.
Compile XU4 on the Pandora
Prepare the environment
You will need an OpenPandora for this.
Install the C/C++ Development Tools. Placing it on an ext2-formated card is highly recommended (and is required for addipk to work).
Make sure, your Pandora is connected to the internet. Enable the SSH daemon by using the configuration tool.
Connect to your Pandora with your user (because it's more fun to use your computer keyboard):
ssh <YOU>@<ADDRESS>
Prepare the compilation target! Most app will compile to /usr/local, but that's on your NAND memory (on the CPU), so let's move the /usr/local to the SDCARD:
mkdir /media/SDCARD/UsrLocal
sudo ln -s /media/SDCARD/UsrLocal/ /usr/local
Make yourself a place on the SDCARD:
mkdir /media/SDCARD/home
Now, start the Development Tools:
/usr/pandora/scripts/pnd_run.sh -p /media/SDCARD/pandora/menu/cdevtools.freamon.40n8e.pnd -e "setup/start.sh"
Provide the password and swith to your new home:
cd /media/SDCARD/home
Download the source
svn checkout svn://svn.code.sf.net/p/xu4/code/trunk xu4-code
Make sure, your SDCARD is ext-formatted!
Prepare the compilation
Edit the Makefile and add the following to the FEATURES to optimize for the ARMv7:
-O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -fassociative-math -funsafe-math-optimizations -ffast-math -pipe
And disable the DEBUGCXXFLAGS.
Compile it
Before you compile it, clean your /media/SDCARD/UsrLocal. You will have to copy the binary and data files.
Now, you need to be patient:
cd xu4-code/u4/src
make
and finally
make install
copy /media/SDCARD/UsrLocal to src/u4.
CrossCompile XU4 with the OpenPandora Toolchain
Prepare the Toolchain
Download the file openpandora_toolchain.sh.
Fix the OPKG download location:
Locate the line
wget -O $TMPDIR/$OPKG_ARCHIVE http://opkg.googlecode.com/files/$OPKG_ARCHIVE
and replace it with
wget -O $TMPDIR/$OPKG_ARCHIVE https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/opkg/$OPKG_ARCHIVE
Change the file permission to allow execution:
chmod a+x sdk_installer_openpandora_toolchain.sh
and launch it:
./sdk_installer_openpandora_toolchain.sh
It will take it's time.
After it has finished, add it to your path. Edit the .bashrc file and add the following:
export PNDSDK="/home/thred/pandora-dev/arm-2011.09"
export PATH="${PATH}:${PNDSDK}/bin"
Don't forget to restart your console.
Download the source
You can find the source on the XU4 Project Pages.
