「心殺技」Looks like a made-up Kanji compound. "Heart Kill Technique/Art" or if you prefer, "Special Move".
※Command is for when the character is facing the right direction. [Special Moves] have a grey background.
[Blue Box] mark means the Special Move can be performed as an EX Special Move.
[Thunderbolt] mark means the Special Move has Armour Break properties.
[Super Combos] have an orange background.
[Ultra Combos] have a red background.
「同時押し」Press at the same time.
「弱」Weak punch/kick.
「中」Medium punch/kick.
「強」Strong punch/kick.
「連打」Beat/barrage? With the benefit of context, this is obviously "repeatedly press".
「タメ」No idea what this is on first view (and why it's in katakana), but again with the benefit of context, this is "hold directional button". If I was to take a guess, I would say that 「タメ」stands for the verb「溜める」which means to accumulate or collect. In this case, it means to "store" power.
「空中可」Possible (to perform) in mid-air.
「空中で」(While) in mid-air.
For M. Bison:「タメて離す」Hold and then release (button).
For Balrog: 「三角跳び後で追加攻撃」An additional attack after a/the triangle jump.
For Balrog (Ultra Combo right below the above): 「Rolling Izuna Drop」At close range, after the「Flying Barcelona Special」.
