And so I was correct....

I've figured them all out except for venom .... does one even exist? I'm pretty sure I tried every buttom combination =)

i just need to know psylock and guile

i doubt these work but i think
sential is k1,p2,p3
guile is p1,k2,k3
psylock is p3,k3,k2
venom is k1,k2,k3
adn blanka is k1,p2
