"Rough ride" means "difficult" or the like.
I'm very excited about this port! PH abstracts hardware at the lowest possible level, which is very powerful!
Just think of the possibilities. Write a proprietary blitter (fine-tuned for your game), and have it work across many devices and OSes, with the same code running on all systems!
And writing a blitter with PH is ridiculously easy! Great work Thierry, keep it up!
