Imho its all a matter of degree really, take this for instance

Raz has done wonderful work on developing the unibios, at the same time (nothing to do with the above link btw) is/ or has been involved with mame dev. which is fine, wish I had the skills to contribute, contributed some boards for dumping.
With all respect, only 3 years ago Raz would have been burned around here by the neogeonazis, wake up old timers. Thankfully the puritans have wised up or died.
Just my 2c and thanks for your great work Razoola.
