flipperzero-nrf24 VS flipperzero-firmware-wPlugins

I have read through https://github.com/mothball187/flipperzero-nrf24 and https://github.com/insecurityofthings/jackit but I still need help finding something.

so I got my flipper a few days ago and I´m trying to experiment as much as possible. I found you can install a NRF24 board and "hack" into USBs. (https://github.com/mothball187/flipperzero-nrf24) The problem is, I don´t know how to install this files. They are ".c" files and when I upload them to the flipper, they are visible in the qFlipper app only, not in the device itself. So I´m kind of lost here on what to do. Any help will be very much appreciated. Thanks!

Rogue Master Flipper Zero firmware is the best...

RogueMaster, i can only recommend it. (https://github.com/RogueMaster/flipperzero-firmware-wPlugins)

Quick search of Google gave me this which happened to me a while ago, https://github.com/RogueMaster/flipperzero-firmware-wPlugins/blob/420/GAMES_ONLY.md

If I read it right, you have to make changes to the firmware build options and on the firmware itself to get it to run doom. If you're new to it I suggest you don't do that and just get RogueMaster (https://github.com/RogueMaster/flipperzero-firmware-wPlugins) firmware which comes with doom installed. If you're confident you can do it, just clone the firmware, apply the changes listed in the doom project page, build it, flash it and voila :)
