Razer Kishi apps can't check firmware? and Compatibility Issue

Hello guys, before i'm asking i wanna inform the device. I'm using Redmi Note 9 Pro and Razer Kishi v1. i want to ask for version of your Razer Kishi v1 firmware. Because i can't check the last version of this controller firmware. Any other method for update this gamepad firmware? And i have more question, any of you have issue with analog and pad for ppsspp emulator and another game with gamepad support? In my case i can't play Dead Cell with Razer Kishi, it doesn't respond the key. Thanks,
