Ps360+: how to check drivers? How to update them (tutorial is a bit complicated, got questions)?

Hi everyone.

I'm mounting one of these in my best friend's joystick (it'll be his Xmas present!) and I was wondering, is there a way to check what firmware version is installed on the board?

When I plug it in my PC through USB it says "PS360+ v.1.2", does that mean that it's on 1.2 firmware (Xbox 1 support is a priority so I guess I'd have to update to get that working)?

Also, I've been reading the firmware updating tutorial but there's something that isn't completely clear to me (I'm a bit dumb when it comes to this kinda stuff and also english isn't my 1st language), at some point it mentions a hex file that you've got to load...where's this hex file?

Is it referring to one of these (very likely, wouldn't make sense otherwise):



If so, how do you download them? If I click on them my browser just opens up a page full of numbers named http://akishop-customs.com/PS360Plus/Software/OfficialVer1.31.hex, like this:



Thanks in advance for your kind help from a fellow arcade stick enthusiast.
