# Overview
The Replay board is a high quality base platform for the development and usage of “cores“.
Whilst no longer in production, if you have managed to get your hands on one, the Hardware section covers the additional items needed to connect and use your Replay board with a TV or Monitor.
Once connected and powered on (without an SD card inserted) you should be greeted by the embeded loader core. The embedded loader does not currently offer many features but provides a useful way to verify your board is working without the added complication of running a core from the SD card.
If you have a blank screen/no video signal, please refer to the Troubleshooting section for assistance.
Note
Recent cores require an up to date firmware. Refer to the Firmware Upgrade instructions to check your firmware version and update.
Now you know your board works, it's time to download and configure the "cores" that enable your Replay to recreate arcade machines, home computers and gaming consoles. The SD Setup section covers this step.
If all has gone well, you should now be all set to lose yourself in endless hours of retro gaming and computer use. Enjoy! If your setup hasn't gone so well, check out the Troubleshooting section or join our active Community for support.
