Wow, very impressive results there. I was always pissed that SEGA never made a proper MEGA-CD version of GA ( and sooooo many others!) so this looks like a nice alternative, even with the Wii/360 versions I have.
It's a damn shame that NEC Home decided not to make the arcade card/SFII' combo in '93. By the time the arcade card arrived, it was far too late and apart from Hudson's very impressive NEO-GEO conversions, it was wasted. Other AC only games such as Mad Stalker and of course, the giant turd that is Strider Hiryu, wasted their potential.
Strider could most certainly have been a hell of a lot better if NEV had not given it to the crappy, inexperienced team that made it. Just as an 8-mbit Daimakaimura on the MD could have matched the SGX version. Whether ACD version of SH could live up to the MD version, I am not sure. It could have been close though.
As for a 16-mbit Final Fight on the SFC being better than the original, I doubt it would have made much of a difference. The SFC would NEVER be able to touch the MEGA-CD version anyway. That shitty, ancient Famicom processor they stuck in the SFC could never compare to the CPS-I or MEGA-CD. Every beat em up/fighter on the SFC ran at a greatly reduced resolution with only 2 or 3 enemies on screen at a time because that's all it could handle. All the colour in the world could not make up for that processor and it never had a hope in hell of an arcade quality game like Bare Knuckle II. Maybe if the CD system had been released but the arrogant morons decided against that because CD was not the future. That worked out so well for the N64, lol!
