Ok. Right now I'm batteling the FINAL boss for the run. Should be posted within perhaps an hour. :)
Anyways. I menaged to do that backward shooting again.
Think I'm getting control of it.
When you charge the psycho to max, then fire it off, your character won't be able to shoote for some frames. If you hold down the B button he will fire as soon as he can. Right as you do this, turn the other way from where you want the fireball to go. This will make the fireball move the opposit direction.
I've made a picture of this.

As you can see in this case, I want to shoot against the boss, being to the right, just as the ball launches I turn to the left, away from the boss. The fireball now flies towards the boss, but backwards. :)
Funny ain't it? =)
Doesn't do anything special. It's just a graphical bug or what to call it. Perhaps someone else can explain this more in code or something to get a real understanding about it. On the link below I will include a save state which you can load to perform this glitch(?) on your own. All you have to do when you load it is to hold down the B button and hold the left direction as you hit the quick load button. If you didn't understand that, hold left+B-button and hit F8 in Gens to quick load. :)

Not sure if it works at full speed. If not, slow down your emu to 10% to try this out. :)
