Retrogaming, the enjoyment of older computer based games and platforms, has been growing in popularity. I was intrigued a couple of years ago when, at a Vintage Computer Fest, I saw a multigame platform with hundreds of game ROMs copied onto a single emulation device. I had been wondering what the old games would look like connected via an HDMI input as opposed to the old low resolution RF transmitter method.
Then I came across the RetroPie project. RetroPie is a framework, delivered as an image, that allows you to run a number of game and computer system emulators on a Raspberry Pi. RPi models 2 and 3 are much better than older versions for this application. It is very simple to install and I was even able to use an old Colecovision controller to play Donkey Kong, Ladybug, and Carnival.
To connect the old controller, I came across a device called the Vision-daptor. One side sports a DB9 male connector, the other a USB B jack. It arrived just a couple of days after my order. The RPi recognized the device as a joystick controller without adding any additional drivers.
The Coleco emulation is handled by an optional component called CoolCV. CoolCV will also run under Linux, Mac and Windows. If you use a controller, rather than a keyboard, you may need to make some changes to key mappings in a configuration file.
There are plenty of sources for games online, but remember that games may still be covered by copyright. Some folks copy the contents of ROMs that they have purchased allowing them to play games for which they no longer have a gaming device. This requires some specialized hardware.
If you do download games via the internet, keep in mind that some sites may be vectors for the transmission of viruses and other malware. Exercise caution while you kill off those space invaders. And the games do look great on an HDMI monitor!
