Nah you're right, the odin 2 mini has an Xbox-style layout (A bottom, B right, Y top, X left). Nicole from AYN (in the discord) said you can also swap A/B and/or X/Y to get a Nintendo-style layout much like the retroid pocket 4
Not yet (my guess is the software would mimic the Xbox layout by default), but either way you should be able to choose in the OS, just like with the OG Odin & the retroid pocket series. On the OG Odin, you'd go to the Settings app > Odin Settings > Controller Style to switch modes. I'd personally be surprised if the Odin 2 mini didn't have that option, especially with the swappable buttons
looks so compact
