Do you like KOF13's button hold maybe? Complete input, press button and leave it held. For the next ~7-8 frames or so the game will attempt to do the move. If it can, it will. If it can't, it'll wait. Makes combos easier, guarantees wakeup reversal if you want it (but since stick inputs are only checked for validity on button press, you have to tell the game to do crossup. ie. SF4 stores stick information in forward/back format, you press button, it checks those forward/back instructions. So crossing up mid-input can result in crosscut DP being something franken like 621. KOF sees you press button, checks facing of character, reads input buffer to see if there's a valid DP input in there. So you face left, opponent crosses you up, you input 421 or 424 + late P) but would allow a low actual input buffer in neutral.
Been playing GG a bunch and even KOF13's shortcuts are giving me issues. It's wonderful that the game has a built-in override for DP shortcuts (accepts 626 as DP so run~qcf = DP. You can override by tiger kneeing the qcf move) but it's led to me tiger kneeing absolutely everything. A most unhealthy habit in a game as jump cancel infested as GG. ;__;
