MiSTer FPGA Forum

Hi all
I'm trying to make my 8bitdo Pro 2 (wired) controller behave as good as my other SN30 Pro, without success (and yes I plug it in while holding the B button)
For instance in Crazy Climber the SN30 Pro works absolutely fine, whereas the right joystick of the Pro 2 is only partially working in the core controller configuration..

The idea was to alter the mapping in the MiSTer gamecontrollerdb file Pro2 entry, but... Which one of the two entries in gamecontrollerdb was being used?
Neither of them was similar to the IDs reported by lsusb, dmesg and the SDL test utilities - and those info were different to each other, to begin with.
So I've created a new top entry in the gamecontrollerdb file, matching the ID reported by the SDL utility; no way, the Pro 2 is still being recognized as itself.

By the way: in my mind the Pro 2 should have had an ID like "**000000c82d000010300000********" according to the lsusb info, but instead it shows as "03000000c82d00000631000000007200" in the SDL test utilities - and possibly something else entirely during the MiSTer detection, I guess.

Any suggestions as to what I may be doing wrong, and possibly how to achieve my goal? Please find here below all the bloody info I'v ecollected.
Thanks in advance, and apologies for the long post!

Update: I've found a way of making the 8bitdo Pro 2 behave like its sibling SN30 Pro: forget all the above tech stuff, it's enough to plug the Pro 2 in the MiSTer while keeping the Y button pressed (as opposed to keeping pressed the B button, as 8bitdo recommends)
This way the controller is recognized as a "Nintendo controller", and it behaves like the SN30 Pro - as far as I can tell at least
It's listed by lsusb as: ID 057e:2009 Nintendo Co., Ltd Pro Controller
Unfortunately this controller state will disappear when you turn off the power, and turning on the MiSTer with the controller plugged in leaves the Pro2 in an undetermined state, where it isn't properly recognized by the MiSTer and hence not functional at all.
You have to disconnect and reconnect the Pro2 while pressing the Y button, every ******* time you power on the MiSTer

PS: I'm leaving this post as not solved, since my original question still stands:
How can I trick the MiSTer to recognize this controller as something else, by customizing the gamecontrollerdb file?

PPS: why do I need a Pro2 at all, since I also have a SN30 Pro? I have big hands, and the Pro2 feels much more comfortable

I have a SN30 Pro+ which I am very happy with. I'm surprised that 8bitdo changed the Pro 2 so much in this regard. The Pro+ "just works" for me the vast majority of the time.

I definitely understand your frustration here. Hopefully there's a way to get it to behave.

Thanks
I've bought the Pro2 expecting it to be just a straightforward upgrade from the SN30 Pro, which I like very much.
I believe the true upgrade path should have been to a Bluetooth Pro2, as it sports a switch to set it to one of 4 different controllers emulations modes; no need to press anything when plugging it in, I think.
Unfortunately I've discovered all that only yesterday, well a BT Pro2 it's now on my controller wishlist for next time
