After many tries of reinstall Ubuntu on different system(about 7) I have the one that I think is stable and the emulator work.
The system is HP DC7800 E6550/2GB/160GB
Here is how I atached the PC.
Used the original backbox wooden plate.
Use 19" LCD and made bazel for it(sorry no picture of this)
Made custom wall mount.
Use LED strip instead the original lamp for the translite(more efektive,more live,low power,lower heat,cheap) and attached it in +12v rail from the PC PSU.
Use two chains that will hold the wooden plate for future services and of course if it need to be remove the whole plate is easy.Just detach the chains.
To use original speakers bought Lepy 2x40W+1x60 RMS and PC PSU that is more efective than the recommended 12V/5A adapter(don't buy this)
This thing is so creazy until I do i t work correctly.
After many many tries here is the right type of the installation.Tried it on 3 different type of system to be sure that is the right method.
After the standard installation from torrent CD it go to the Fatal Error 4.Of coruse if you boot directly to the game select screen no ned to this steps.After this must be done(you must have internet connection)
sudo sed -i s/us.archive.ubuntu/old-releases.ubuntu/g /etc/apt/sources.list
sudo sed -i s/security.ubuntu/old-releases.ubuntu/g /etc/apt/sources.list
sudo apt-get update
May stuck on 99% at package 32,but will quit afte a while and you can continue with these commands:
apt-get purge lxdm
mv /etc/lxdm /etc/lxdm.orig
apt-get install lxdm
cp /root/pinbox/scripts/pinbox.dekstop / etc/xdg/autostart
rm /etc/init.d/pinbox(very important line,if not the emulator will not boot directly to the game select screen)
Now the game boot to the select screen.With pressing F1 key you are in GUI and can change the boot order to RFM or SW1 from Pinbox configuration.
Printer configuration(from BIOS):
HDD(used some partition manager of Windows):
sudo apt-get remove xscreensaver
Now it left only to find a way to remap or something else the power button.
I want when I press it to quit/power off the PC.
The sitaution now is this:
In Ubuntu GUI,no problem,it shut down,bet when I'm in the emulator(the game is running) nothing happen when I press it.
I must press F1 to go to GUI and after that if I press it the PC turn off normal.
The idea is if I can remap somehow power off function/button to work like F1 button.
If it was Windows,no problem,but Ubuntu is hard for me.
