Custom arcade stick question.

I built a stick a while back with arcade parts and a hacked controller. Why won’t my stick work with any of the KOF series or Blazeblue? It works awsome with SFIV as well as many of the arcade game I’ve DL’ed, but these two imparticular won’t work. The stick itself will move the characters however none of the buttons will respond except ‘X’. The games will recognized them when they are pressed during menus but not during play. It’s kind of frustrating, don’t know what I may have done wrong if anything.

What controller you used for the PCB?
And are you using the PS3 or Xbox 360 version of KoF XIII?

The PS3 version of KoF XIII have serious issues with controllers that are not PS2 game compatible.
