Is this an actual release or a nebulously-licensed dump of some random port? If it's the former, that's awesome as this was one of my favourite games as a kid.

I don't remember Speedball 2 having a DreamCast port, so these repositories seem somewhat strange. They are also strange for missing license files and various other asset files.
