this is normal python? https://reticulum.network/ can start on it?

I recently ordered a PCB from Japan and am waiting for delivery. May I install all the parts, including the RFM95W and the SD card reader?

I know I will need to rewrite the RPi, but if I do, will I be able to use both the Armachat and the retro computer emulator in one PICOmputer BOX?

I think with little modifications yes. there is solder jumpers on board and you can move LoRa CS signal to another pin and you can use both, but then for gaming and communicator need upload new firmware, because retroemulators are in native C and armachat is witten in python

1. Will it run if the RFM95W is not mounted?

2. Can the Pico be replaced by a Pico W? (so as to possibly in the future add WiFi to the functionality) 

thanks

1. for retro game emulation yes

2. I have soldered but untested, pinout is same, I do not know how it work behind some layers of coper
