because of Street Fighter, the plan initially was to do a 6 button PCB....
but after considering which other games would suit the 6 button layout, i decided against it.....
not many games really suit the 6 button layout (only a few at best)
the ergonomics of having 6 buttons in so close proximity to the joystick also doesn't feel or play great (IMHO)
plus i'd have to remove the B & A lettering on the case/shell or have the L1 & R1 before the B & A (just a messy setup, again IMHO)
there hasnt been a joystick PCB for the Game Boy....
thats the reason i came up with my own...
(i've basically ripped off Helder common ground PCB and replaced the Dpad with a joystick


the joystick is designed to work with a PSP1000 thumb cap, but even on the PSP it isnt the best
(i've got an after market thumb cap on my PSP)
so keeping with the Nintendo theme i've used a 3DS thumb cap, the feel and play ability is a lot better than a PSP thumb cap
(ive had to combine the two, pretty much the same as Kayumba has done in his CM3 build)
