Bluetooth Controller works on emulationStation but not in ROMs (IPEGA-9021)

Re: ipega PG-9021 partial mapping

Hello! I've successfully paired an IPega-2021 controller and it works just fine on emulationStation, however, when I enter in a game, the key mapping in simply ignored (eg. my hotkey is now my Xbox's A button). This also messes around with my wired-connected Xbox controller, making it's key mapping being also ignored.

If I reboot and don't connect my bluetooth controller, the Xbox controller works just fine...

In order to make my bluetooth controller work, I've connected it on the Bluetooth menu, created the udev rule. I've also installed the xpad driver (I don't know if it is required but I've read somewhere that it could be necessary).

As it happened to anyone?

Test1 - I've uninstalled the xpad driver and noticed that when mapping the bluetooth controller again, my right-trigger was skipped. Also, When I booted the game, it had the exact same behavior
Test2 - Messed around with retroarch and remapped the keys, and tried with both udev and sdl2 (as stated in this post)

No luck on both cases

@in2ition You can try looking at a similar iPega controller which had the same behavior:

@mitu Thank you for your response. I've already seen those cases, however I cannot reproduce the same behaviour . The second like you posted does not help because I'm able to use the controller on ES. The first link I cannot really follow because when my Xbox controller AND the IPEGA controller are connected, both key mappings get really weird...
