OK, this thread inspired me to post a few thoughts

on the use of "arcade perfect" terminology and why it is a relative term:
0) Back in the day, many ports seemed to *really capture* the arcade experience, in terms of gameplay, graphics and sound. Today, we look back and realize that the consoles of yesterday didn't have many (if any) arcade perfect ports. Even simpler arcade games like Galaga were lacking / different in significant ways.
1) We still don't have truly "arcade perfect" ports on today's high-end hardware / consoles. Do many of these ports *seem* nearly perfect? Of course. Well, at least in 2005 we think so...
2) A few years from now, though, people will laugh at our current emulation of arcade hardware, because significant improvements will be made in all areas. Perhaps only the purists will appreciate this, because most folks are happy with the current level of emulation of older arcade games, but improvements will be made.
So,
A) "Arcade perfect", depending on how strict your standards are, is a term that shouldn't be thrown around carelessly with ports. EVEN TODAY.
But,
B) If we judge a port in context to the available hardware at the time, we can better appreciate the ports of yesteryear. In the realm of
computers X68000 had a wicked port of G n G. But we should distinguish between platforms and not simply lump X68000 (or AMIGA, for that matter) in with relatively cheap consoles when we make comparisons.
We should also be a little forgiving when folks (back in the day) extolled a game as "nearly arcade perfect" because, at the time, these ports were as close as any console had gotten to recreating more sophisticated arcade games. We're talking late 80's and early 90's.
Sure, there were great ports of simpler, earlier arcade games (i.e. Joust, Galaga) during 8-bit and prior console eras, but it was amazing to see STRIDER on the Genesis at the same time it was in the arcades. Yeah, I know that Strider on Genesis wasn't arcade perfect -- far from it. I also know that folks have argued that the Genny port is showing its age and had some flaws. I don't disagree. But I still enjoy the game -- and it is NOT about nostalgia.
I seek and enjoy most versions of a kool game. So...
C) I never understand folks who say, "Well, now that the we have the perfect Saturn / DC / PSX / GBA / PS2 port of ____________ , you shouldn't waste your time with the earlier, lesser ports." In all fairness, some of the folks who say this aren't interested in retrogaming on consoles as much as they are interested in the orginal arcade games.
Sorry for rambling
