Fuji emulations seem good., but I'm not crazy about Cobalt's system or company: you have to buy the basic camera pack first (which I've done). If you change cameras (which I've done) you have to buy a new basic pack for the new camera and the previous one is now wasted. There ought to be some form of trade in. On top of this, as a company Cobalt are rather limp. I've found their web descriptions confusing and dont always work well on android. I've emailed to get clarification and point this out and foudn the'clarification' to be just as confusing, I also had an email about making suggestions to help improve the website and rewards for the best suggestions. I sent a long email (because I'd like to see the company do well). Did I get a reply/acknowledgement/thank you? Of course not
