Capcom Classics Collection Volume 2

Sometimes the game locks up after the stats screen in versus mode (the screen showing how many wins each character has)
Sometimes when a character does his or her special move, a sound from a different character's special move comes out instead. This has been noticed with moves like cammy's thrust kick, fei long's chicken wing, balrog's TAP (like "FIVE!"), T Hawk's typhoon, DeeJay's max out, and others. The author of this hasn't recognized it happening more with one stage or character more than any other so far. Happens in arcade, versus, and training(?).
Sometimes the music on the game's various stages slows down noticeably for extended periods of time. Happens in arcade mode.
In training mode, when a character is thrown at zero health he does his death scream and the game slows down as if the character had died, but the game then continues normally.
In training mode, some moves done while a character is at zero health cause wrong reactions to the dummy (such as Honda's ochio throw sometimes).
In arcade mode, using Zangief against Hawk on Hawk's stage, not only did the music slow down, but the game got sluggish as well. I couldn't tell if the game was moving slower or if there was some lag in the inputs, but as soon as I moved on to the next stage the problems were gone.
The 'easy specials' cheat can apparently cause glitches when the AI is playing with it on.
Q-Sound emulation is highly inaccurate.
