hi people, on 5 or 6 days ago i find a neogeo mini on a super market on my city, the first thing i do with my NGM its the battery mod but during the mod process i find that stick problem occurs to many people after flashing their units so i decided to wait and no screw my new unit so a 2 days later one guy comes to my electronics workshop with a after flash joystick problem, well i don't promise a fix for his unit and after he's accepted my condition the first step to do and works for that dude are the joystick replace for a ALPS analog stick we used a lot for fixing xbox 360 controllers, i don't believe how crappy are these sticks that are using SNK on their neo geo mini elaboration, you need to mod the alps stick cutting the microswitch pines.
sorry for my english, i only registered on this forum for helping people with the stick fault i don't expect credits for this hehe.
