With the current release of Damon V. Caskey we put a complete change of topic on the parquet. Away from hardware, towards software. And away from vintage towards the modern, but without losing sight of the beloved PixelArt, sprites and typical scroller games.

If retro-style games are your thing, and you are currently working on one yourself, then Damon's project OpenBOR might be something for you.

OpenBOR is a royalty free sprite-based side scrolling gaming engine. In development since 2003, the project has reached a level of maturity that makes it unique in the 2D side-scroller space.

With ChronoCrash there is a lively community around the project, a wiki, a forum, a Discord server and lots of fellow developers, who are happy to help with your own projects.

Thanks to the engine you can quickly achieve results without a high entry barrier. You end up with a product that is hardly inferior to former triple-A titles. Exactly your topic, then you can't avoid OpenBOR.
