So i got a mayflash arcade stick for cheap and decided it would be a nice little modding project. Took out the stock stick and buttons and replaced them with a Ls - 32 and some white sanwa buttons i had in my toolbox. It works perfectly fine for ps3 (other than not having a home button…) and pc.
The only issue i’m having is when i plug it into my ps2 i have no directional control at all. All the buttons work fine but i can’t move around any menus or move my character around etc. Note that this only happens on the ps1/2. If i plug it into an inpin or pelican converter for ps3 or pc the whole stick works fine. Does anyone here have any clue as to what could be causing this? If it matters i am using the stock pcb in the stick. I believe it is the 4-20-2009 model mayflash stick. ie. the non common ground one.
