there's an option in training mode to display the recovery animation, it does this by highlighting the characters in a light blue shade when they are stuck in an animation (blocking, getting hit, performing a move, etc) and reverts them to a normal color scheme when they have recovered. better than nothing i guess
so if you wanna see if something is plus or safe or w/e, you put on the option on and set the training dummy to block, if you revert to the normal color shceme first, it's plus, if you both revert at the same time, it's 0, if the training dummy reverts first, it's minus.
hah, i remember in some video, i think mikez (developer of skullgirls), saying something about how he put framedata to appear on training mode, he was questioning why this isn't like, in every modern fighting game, and i also think that he mentioned implementing it in one afternoon (or was some other good feature i don't remember now)
@Sotherius i remember harada saying something to the efftect of having in game frame data makes the game too easy to figure out, and that it takes the mystery away (i'm hella paraphrasing here), which i think is friggin stupid, but hell, its his game, let him do what he wants
