Here's another nice clear video of a decent game on a machine running code 1.14 from new owner tehashix:

Pinchroma also offered the following information as to why JJP decided to use a PC-based system in the game:

"The PC based decision was actually an easy one.  We selected a military grade motherboard and are driving the game with a solid state hard drive with a 50 year mean time to failure.   The way I wrote the OS is utilizing a mechanism called UEFI which guarantees infinite forward compatibility.   As motherboards grow obsolete, they can be switched out at the owners discretion with NO additional work.  Literally swap the board/CPU like you would on any mpu on an existing pinball machine and the game will boot right up.   The drivers are universal due to UEFI.   10 or even 5 years ago this wasn't possible. 

Not only are we driving full 1080p which isn't possible in an embedded platform as you need a gpu but we will have full gigabit Internet access for downloads and Facebook syncing and a bunch of other things I can't announce yet that also will never be possible with traditional embedded."
