it's a shame when someone quits the scene. but it is understandable. on this side, we the "users" are pretty often shielded from what the emu authors have to deal with sometime - i mean when you put up a website or whatever, do an interveiw and offer your email address, then you are opening yourself up to the mercy of the public. It's true, we like to think that most people are respectful of this, sure once in awhile people may get a little short or naggy but that doesn't seem too bad..
unfortunately, some folks have a little too much time on their hands and can just be plain childish and inconsiderate. when they don't get what they want or they don't get properly pandered too, they can do things rashly (like send tons of hate mail.. or worse) Years ago someone made a Sega CD emulator (years before a public one was released!) .. she was doing it for a school project, and out of kindness was sharing notes of her progress with the scene.. unfortunately her progress wasn't as fast and available as some in the scene would have liked and she got a whole bunch of hate mail, even death threats and things. It sounds pretty retarded but it's not unbelievable, at any rate she rescinded her participation from the scene at that point, finished up the project privately and that was the end of that... I think she disappeared from the scene altogether.
That story sucks, so do the ones we have seen around here recently (and don't forget about what happened to realityMan and Epsilon, creators of UltraHLE!) Talented people all forced to quit the scene for whatever reason. Anyway my point in posting this stuff is things happen that we don't hear about, maybe this guy (Pirotic) was getting mailbombed or whatever day after day, he sure got kinda shat on in the forums. No one has to put up with that stuff if they don't want to - they work for free - and sometimes they return to the scene, sometimes they abandon it altogether (you think we'll ever see any more work from Intellecto? Doubt it..!)
Anyway try not to blame these guys, they are working hard for free and sure, it sucks when the scene drags and we get hyped about things after seeing all those mouth-watering screenshots. Just remember that "emu authors are people too"
GBA scene is lucky cause they've built up a strong community of emu athors who are very active in the forums (not just dev-specific ones) as well as prolific with their work, hopefully we can get the GP32 scene to be more like that (so that the authors don't seem so distant and unreachable) - it would probably bring the authors + users closer, there'd be less of this hate-mailing and trash talking.
