Hi so i am modding a gba and all was going good all buttons wired and working until i realised there was not enough space for all the bits so i removed the centre green section of below main board GBAtestpoints.jpg below is attached a "rough" pic of my wiring the yellow lines are the copper wire it ...

hi i noticed you cut the mainboard cutting out the main green part so just had the pads either side, how did you wire either side?
i know it has something to do with the ground but how would you wire the a/b/r buttons to the otherside?
thanks for your help
also great build!!
