I have used this particular dpad long time ago and played MK3 (PC / sega) and UMK3 (Sega), and I got used to the default controls back then, I don't know if you used to play the default buttons too.
HP FS HK
LP BL LK
because of this, I got myself the HFC4 which kinda look similar to the sega pad, and set the same buttons as the sega, but because of the EX, where I have set the block to be the Circle / 4, I'm not able to perform the EX's properly on that setup, especially when there's a combo and it includes an EX move in between.
do you use your thumb to perform Exes ?
Btw, which dpad you're using ?
Thanks
