i got the mayflash adapter cause the one boom linked me gave me some extra 10$ canadian tax, too broke atm for that but hopefully this thing will still work
in order for it to work it would greatly benefit you to do all of the following
1: CALIBRATE YOUR CONTROLLER
if on windows xp or vista find "game controllers >>> settings"
if on windows 7 (dunno why they'd **** with this..) go to DEVICES AND PRINTERS then RIGHT CLICK the game controller icon to enter game controller settings(you can also probably find this inside system32 somewhere but i have yet to try)
2:FOR THE LOVE OF ****, USE an N RAGE PLUGIN
and map your buttons with a high deadzone at first so you can easily map them
use whichever you like best, i prefer either N-Rage`s Direct-Input8 1.6X OR N-Rage`s Direct-Input8 V2 1.83
3:UNCHECK RAW DATA, ALWAYS AND FOREVER. ON EVERY CONTROLLER SLOT AND PLUGIN, NO EXCUSES
EXAMPLE:
THEN
i did this at a friends house and we were playing PERFECTLY with BOTH controller slots so i guess ppl are just noobish in saying/experiencing that only slot 1 works, lmao
good luck
