Thanks for the update Calamity, I didn't want to make it look like I was whining about that, again I took that particular event as an example to illustrate what I was saying (that it's absolutely great that MAME evolves but when it breaks stuff that was only in alt builds and people really care about it's natural they would turn to baseline and come ask 'why, Gods why' ^^). Thank for your hard work as always of course. (PS: why not skip the public release of GM 0.172 if you're too busy? I think people would totally understand)
Going back to the topic of useability and command line, I understand that it's better, more powerful, that you guys like it for that. But again that's from your perspective as computer-savvy people, even genuine experts for many of you I believe. I'll remain convinced your experience is clouding your perception of how normal people deal with that, as a whole command line I'm still sure of it is a no-no, it is not the kind of controls means the majority will expect and you won't change them without a strong engagement to do so (translation: more trouble/work for you whether it's through development or support). And again I don't blame you (you devs are too quick to think users think ill of you, as much as they think you think ill of them maybe, it's really like two different cultures struggling to communicate), I just think you have a strong IT crowd perception and you don't realize how different you are from people who are not from this world and where they're led to by the market as common users, customers, workers, whatever.
In yet other words, something like command line is diametrically opposed to people's tech reality, you can't tell them it's their fault. Call that a culture of ignorance if you want, you're the only ones judging if you have to adpat to it, or oppose it.
It's your baby, but would you make a poll call for anyone to tell what they think about command line vs. UI or .ini as means to control MAME, I would bet the results to be quite predictable. No need anyway since you've stated that things would eventually move to UI in the future.
Please don't give what I'm saying more meaning/weight than necessary (I don't think you would anyway) I believe I'm right on that particular point, but of course I'm only one individual user stating his personal opinion and babbling of course, with an unhealthy amount of redundancy because he's also trying to explain his point to several different people who know better.
