Final Fantasy III: Imp's Retort

There is a bug called the "Psycho Cyan Bug" which is the result of two bugs. One of these bugs causes Cyan to counter the first physical attack by anyone against anyone with Retort if he is defeated and then revived after preparing Retort; there is already a patch that fixes this. The other bug causes Cyan to counter any physical attack against him if he is transformed into an Imp after preparing Retort, because an Imp will Fight instead of using Retort, and thus the game does not realize that Retort was used. The combination of these two bugs causes Cyan to attack repeatedly until the battle ends. This patch fixes the second of the two bugs.

PURPOSE:
There exists an infamous bug, the Psycho Cyan Bug, which can be exploited to make Cyan attack repeatedly and endlessly. It's actually the byproduct of two bugs. The first has been fixed by Terii Senshi's Psycho Cyan Bug fix patch: if Cyan is KO'd after readying Retort and then revived, Retort will activate in response to any subsequent physical attack by any entity against any target - even if Cyan is not involved.

The second is fixed by this patch: if Cyan tries to Retort while Imped, he will Fight instead (because Imp prevents Retort) and Retort will still be set. The combination of these two bugs allows Cyan to counter his own Fight with a Retort, replaced by a Fight, which will then be countered as well, creating a nonstop cycle of attacks. Terii Senshi's patch fixes the first bug, which is enough to fix the Psycho Cyan Bug; however, it does not fix the second bug. This patch does so.

There is a problem that occurs if you have also applied Assassin's "Jump Megafix" patch. That patch jumps to a section of code that is modified by the current version of this patch, and it causes weapon data to not be loaded when Jumping, resulting in no damage ever being dealt. For this reason, compatibility patches have been included that should be applied after "Jump Megafix", but they can be applied either before or after this patch, and ONLY if BOTH this patch and "Jump Megafix" are applied. Also, make sure you apply the correct compatibility patch depending on whether you apply version A or B of "Jump Megafix".
