Look, his credibility can be argued until the end of time. No one disagrees that he was stupid for not crediting the proper people.
In the end, he has created an amazing ROM, and arguably the BEST 6.5 ROM to date. He is banned from the site (and rightly so I'd say), but his work is far from mediocre. This ROM is amazing
I don't know if he made it all himself, nor do I care. Whatever he used and whoever from, its a nice ROM.
