This is an issue that I’ve experienced and noticed other people complaining about on gamefaqs.com. However, I’m not a member of that site and I don’t think a satisfactory conclusion was reached, so I’m posting it here in case it helps anyone.
When attempting to perform an oil slide (qcf+p), some people often find an oil rocket (360+p) comes out instead. This nearly always whiffs (causing Hakan to exclaim “Seriously???”), and the long recovery frames give enough time for the opponent to punish with just about anything, including their ultra. This can make the difference between winning and losing, and it’s frustrating especially since the oil rocket wasn’t being attempted in the first place.
This happens because the game has shortcuts that mean the full 360 motion doesn’t need to be performed. The oil rocket will always come out when BOTH these 2 conditions are met:
You were holding back to block before inputting the qcf+p. For this reason, it’s most common when trying to block and punish. (Note: Holding downback doesn’t seem to cause any problems.)
You overextend the qcf movement, ending in the up-forward position. This may be more common for stick users, who may use a quick hand movement to execute the qcf, flicking the stick from down-forward to forward with the backs of their fingers. (This never leads to misread inputs when using a shotokan character, so may be an easy habit to get into.)
Since not holding back to block before attempting an oil slide is impractical, the only solution is to ensure you do not end a qcf motion with up-forward. I’ve tested this in training mode, and as long the motion doesn’t end in up-forward, Hakan’s oil rocket will NEVER come out by mistake. When using a stick, the easiest way to ensure this is to consciously hold the stick in the forward position until you see the oil slide happen on screen, before putting the stick back into neutral. A good way to practise this in training is to record Ken performing an HP Shoryuken, then on playback STAND BLOCK it, and punish on landing with cr.mk, qcf+p, p. Once this is consistent, there should be no more problems in real matches.
A lot of people commenting on gamefaqs mistakenly assumed the problem was caused by players not putting the stick back into neutral after blocking and before attempting an oil slide. Therefore they mistakenly assumed that the solution was to ensure the stick went back into the neutral position before inputting the qcf+p command. However, I’ve tested this in training and have found that putting the stick in neutral makes no difference. **B, [neutral], D, DF, F, UF **WILL result in an oil rocket every time, unless the stick is left in neutral for a long time. (When I tested, I could leave in neutral for over half a second, and the misread input still occurred.) Thus, the only solution to this is what I have written above.
If anyone is experiencing any other input problems with Hakan they would like to discuss, please feel free to use this thread.
