Transform Your Android Phone Into a Handheld DIY Game Console
Android: If you just want to play your favorite game, perhaps on the go, a good emulator will do the trick. If you have an Android phone or tablet, it’s easy to turn it into a portable console. Here’s what you need.
First, you need to find out if your device is OTG compatible (on the go). This means you can control your Android device with a game controller by connecting it with an OTG cable. Do a quick Google search for your phone make and model and “OTG support”. You can see at a glance if your device is supported, but if not, CNet suggests using USB OTG Helper , a free rooted app that will tell you if your device is supported.
Once you know your phone is OTG capable, you can buy the cable from Amazon for $ 8.99 on sale. Then you can use it to connect your Android device and game controller via USB. Download and launch your favorite game emulator, then play. You can even cast to your Chromecast device to play on the big screen, but the tablet is large enough for many games. The video above from buaydianway shows what the final product looks like.
