mate sorry to hear that, I do not own the code and really do not know too much about coding you should open a issue on the repo or the repo of original port, but they had no changes on years.
Thanks for the write up! I complied the newest version but was wondering how do I turn off Mario's instant turn? In the original game he does a 'circle turn around' after jumping. I see that was removed (it was strange behavior to begin with)...
