I am here to seek some help on modding my Mayflash arcade stick. I bought this stick a year ago and enjoyed it until the buttons and joystick became unresponsive, so then proceeded in buying a Sanwa JLF stick and buttons. So far, I have been able to solder the buttons and they work successfully. Then when I tried to solder the JLF stick onto the PCB (see picture below; I desoldered it), the PCB starts to overheat and my computer does not recognize the Mayflash Arcade stick.
If you see in the picture (on the right), the white connectors (whatever they’re called) are gone. I was wondering if I am “screwed” or not when trying to solder the joystick to the PCB?
