I think I would refute the notion that these are games that require close to frame-perfect precision which seems to be kinda implied by some of these posts and it's not really as devastating as some in this thread make it sound. Mega Man games definitely require a degree of precision but in terms of input time they're fairly forgiving. With or without the turbo mode, the games are completely playable and I don't think any veteran will truly be thrown off to the extent that has been described here. The audio lag is certainly the bigger issue.
