Mayflash arcade stick

so, I bought a mayflash ps2/ps3/pcb arcade stick and works just fine, however I would like to mod it with my xbox 360 TE stick.

question 1: Is this PCB durable/reliable / “quality”

question 2: Is the Mayflash PCB common Ground?

I just got to know this before I even try to do this, since I don’t want to waste my time for something it might die a few days later.

thank you

2009 is non-Common Ground.
Pre-2009 is Common Ground.

I have my mayflash for a while now with it being mod with sanwa buttons and the JLF.
Its been about 7 months now and its really good if you can take care of it
