help with sega gen controller pcb

[ulao]

Hi al I tried to make a pcb to emulate my sega 6 button but I have two issues.

1) I'm not getting the higher buttons  x,y,z
2) up and down are alternating when either re pressed.

pretty sure (2) is because up and down are connected to the other multiplexers. Since something is wrong they are showing osculations. but I'm not sure what I did wrong with (1), maybe my counter set up?




this was my go a it. Can anyone spot my mistakes?
