@helcril I don't have an Rpi4 and I can't test it, but an Rpi4 has a different architecture than Windows, so differences are possible, not to mention that although Rpi4 runs dreamcast relatively well, unfortunately it's still not perfect due to hardware limitations, so not all games are compatible.

But, the thread will remain open in case someone who has an Rpi4 can test and confirm if it runs or not.
