hi, i want to do a project and i would like to know if rockpi 4c is what i need. I have a JXD s192 android console with 32 bit soc tegra k1, (attached photo) but I am stuck on android 4.4 kitkat, I wanted to replace the motherboard with the rockpi 4c, and here are my doubts:
1- I want to put an hdmi controller board To the original screen, which is 1920x1200, the rk3399 can run eg ps2 or dolphin emulator. Or will I have to switch to a 1280x800 screen for it to work properly?
2- I want to connect a battery between 10000mha and 15000mha, the rockpi 4c can work with battery ?. Android can read the battery percentage?
3- I want to cut the motherboard of a controller in half, add it and connect it via USB, the best I can think of is a ps2 controller with a USB adapter, will it work? or if someone knows something better to tell me (I accept suggestions)
4- I would like to install android in ssd nvme, and not use emmc, is it possible?
5- Could you put a power button on it, and turn it off by software? Or how would it work?
