Just the thought of "XTREME JADE" makes me want to wretch...
As for the TMNT game, it's a damn shame that Konami lost their touch for side-scrolling beat-em ups.
Truth is, though, as fondly as I remember the arcade games, subtract the element of quarters and there isn't much left to go on. When victory is assured because you know you have enough credits, the game rapidly loses its appeal.
We need a beat 'em up RPG, one that allows you to pick new moves to learn, rather than your existing ones simply becoming stronger.
