As you probably already know, a year ago we announced that RetroArch would be releasing on Steam. We have worked hard on this for a fair while now. The process is slower than expected due to reasons beyond our control.
It’s been a lengthy process and we have had to significantly retool things to conform to Steam’s policies and guidelines, one of which is no Core Updater (just like on Google Play now).
While we wait for our release candidate build to be manually approved by Steam (which we’ve been told is a lengthy process), in the meantime we will start giving away beta testing keys. We want to gather as much feedback as possible from users so that the final experience on Steam lives up to people’s expectations.
So with that in mind, we are giving away keys for our first beta test version, Beta 1.
