Well I guess the W/B rights holders(PPS?) had nothing better to do and sent Soren a C&D letter about his patches to fix BROKEN code. I don’t know for sure if this happened but he does still provide patches for DE games on his website...
He wasn't selling anything. He wasn’t even providing patched code. Just the patch itself.
I guess they used the “reverse engineering” clause.
What’s next? Pinsound? ColorDMD? PinBrowser?
