After a few hours this morning, I plugged in a keyboard via USB, and was able to navigate VERY VERY MINIMALLY, literally "emulationstation" and then made it so retropie auto boots without needing a command to do so.
I was able to get the retropie to recognize that there was a controller connected, by going into it's settings and connecting it via Bluetooth. (This was done by going in to retropie settings and that dumped me to a bios looking screen [not sure what that's called in Linux terms] and to have that connected there.
However this did not allow me to set it up in retropie (go figure).
All it does is recognize that there's a controller connected, nothing more. Can't configure anything though, it doesn't go past "hold a button to set up"
I've loaded roms on to the micro SD card, ONLY in a directory "snes".
Done similar to a USB stick, 4gb, in to both the main drive (no folder) as well as into a folder for each game AND also in a folder labeled "roms". Again in this roms folder I've loaded all 20 ish roms directly into the folder as well as in to sub folders with each games name.
NONE of the above worked to have the PI even notice that they were there.

So please assist me, the "progress" was made with a YouTube video. Certainly didn't have any epiphanies overnight lol

@capninja said in Understanding the code:

Is there some game or interactive way to learn about code language and linux (on Raspberry)? Messing with Raspberry the curiosity itch caught my back and I can't scratch enough. I don't wanna just copy texts and press enter, but know why make such decisions.
I don't know if I made myself clear, thanks in advance.

If you're new to coding I can suggest you to start out with C programming. C is portable and universal, many popular programming languages are influenced by C such as Java, JavaScript, C#, C++, PHP, Python. So after learning C these languages mentioned will be very easy to learn.

IMHO the BEST C book is: C How to Program by Deitel. It also covers secure programming and C++. C Programming Language by Ritchie Dennis is also a great book but not for beginners. Avoid the for Dummies books, they're horrible.

Bjarne Stroustrup has written a couple C++ books, they're considered one of the best C++ books. I have them in eBook format but I'm still on the Deitel book.

Most emulators are written in C/C++, the Pi supports C/C++, Linux was written in C. So IMHO better start with C and later C++ and good luck with your coding journey, it will be a lot of fun!

@herb_fargus Thank you!
