I've worked on a few emulator projects and have been in emulation channels for 13 years now, and I do not know of anyone major into emulation who would bash collecting games. I *LOVE* emulation myself for a few reasons. Easy of finding a game, I just go through a list. Bad batteries do not eat your saves in the middle of gameplay on an emulator (Damn you, Link's Awakening DX!). But for me, the MAJOR reason I love emulators, if I can't play for more than 5-10 mins at a time, I don't want to play level 1 over and over and over, I'm busy damn it. Hence, saving anywhere with saved states rock.
While I hate people who bash collecting games (Jelly bastards), I don't like how people outside emulation bash emulators thinking they're "imperfect". My crappy old nes is imperfect, half the time links life bar is all 999999999999 rather than lines. With some exceptions (Sony systems in general, newer systems, Saturn\DC, XBOX ect), you can't see the issues with emulators. Different chips inside different hardware releases cause more issues than you'd find in established emulators. They almost always have better support than the console-on-a-chip junk you see now a days.
