Fine, a MMJ mini review
The device is a little purple box, it does look a bit out of place beside your neo but I guess you won't be looking at the thing when playing games.
The buttons are laid out as so
Select - Select
Start - Start
Triangle - C
Square - A
X - B
O - D
You can program it to use turbofire on A,B,C,D by pressing down R1 then pressing A,B,C or D and letting go. Then when you press R2 it will autofire that button. Being honest I'm not that happy with the button layout but at least most beat em ups allow you to change it in game, and for metal slug the current layout of buttons is fine but for long combo's you'd as always be better off with a real stick. The other top buttons L1 and L2 toggle slow motion off and on (i.e press pause lot's of times and will piss you off in many games if used).
But, I guess this convertor does do it's job and is very cheap. Just it looks and feels it too.
