Probably you are well aware that fans of video games know no boundaries. This is manifested by the constant attempts to run someone's favourite titles on more and more strange devices (e.g. fridge). 19-year-old Twitter user Raio_Ken, a.k.a. Ryan Edgar, boasts of a working copy Doom running on McDonald's electronic cash register.
After visiting the local McDonald's, which was getting rid of outdated cash registers running on Windows XP, Ryan managed to take home one of them. In a private conversation with Kotaku Australia, the 19-year-old told the editor how he fired up Doom on this device.
First he downloaded the ZDOOM port to a USB flash drive, then connected the device to the cash register and activated the automatic boot option from USB. This made the port placed on the flash drive run smoothly on the cash register. Plugging in the mouse and keyboard wasn't a problem either, because Raio_Ken did it with a USB splitter. As you can see in the picture below, in just a few simple steps you can run Doom on a McDonald's cash register.
Ryan also fired upexplorer.exe through the Task Manager, which was launched with CTRL + ALT + DEL, but it was strangely encoded and could do nothing more with it. When asked what he was going to do with the device, the teenager answered that he might use it as a second computer and try to run Sonic Adventure 2 on it.
