Capcom vs. SNK is a tie between Dreamcast and PS2. Evo actually used the Dreamcast version for a time. Both are nearly arcade perfect, but I believe the PS2 is a little faster than the arcade. I believe Dreamcast is 98% arcade perfect though.
PS2 is played more than the Dreacast version because PS2 version is domestic while Dreamcast was Japan only.
The XBox and Gamecube versions are not closo arcade perfect. Roll cancelling is removed, EO groove was added, as well as modifications to P groove. Not worth playing at all.
Marvel is easy. Dreamcast is the best version by far. Everything you can do in the arcade version, you can do n Dreamcast. Timing is the same and everything.
PS2 and XBox versions suffer from sound glitches, slowdown, and some input lag. Everything is different as well as timing on combos. Not preferred for practice. Though many believe if you must play any version, play PS2. Some believe otherwise. But neither compare to Dreamcast.
Alpha 3. Alpha 3 unforunately does not have a huge tourney scene anymore. And throughout it’s span serious tournaments were always done on arcade cabinet. Final Round, the last major safe haven for Alpha 3 still runs it on cabinet.
If you must play on console, then the PS2 version is the best. Pretty much arcade perfect. It was released around 2005 or 2006 so it was a day late and a dollar short. But most console tournies run this version, those that still play the game.
PS1 version was considered a good practice version of thee game. It still had many things in the arcade, but included console exclusive characters.
Dreamcast version was a port of Alpha 3 Upper. Not only does it include new characters, but feature major gameplay changes. Due t the fact that tournies were still arcade based, many did not take this version seriously.
Third Strike has similar controversy to Alpha 3. But Third Strike was worse. For years the only version of Third Strike available on console was the Dreamcast version. This was not arcade perfect. It was a port of version B which was not widely available in arcades. As a result tournaments were always run on version A. Dreamcast was not considered a legitimate version of the game.
In 2004 XBox and PS2 received ports of Third Strike. They were better than Dreamcast because they were ports of version A, which was still common in arcades. But both version had major speed changes, with Xbox running too slow and PS2 running too fast. Top players believed that these differences were enough to not take these versions seriously.
However major tournaments started running PS2 version regardless, and this became the console standard despite pleas that it wasn’t completely arcade perfect. The lack of Third Strike cabinets made PS2 the standard in American tourneys. Still some debate tht XBox mimics the arcade speed better.
Despite that so of the top Third Strike players refuse to play anything but the arcade version. Which has lead to some alienation of Third Strike at Evo.
