Okay so I figured out what was going on. I had two micro-usb cords, one was connected to my RaspberryPi and one to my laptop. The issue was with my micro-usb to the RaspberryPi, it was powering the Teensy LC but not reading it.
I switched the cords and it started working on the RaspberryPi.
You can imagine how frustrated I was, given I am new to all this.
It's held together with hot glue. One of the thumbsticks is messed up. Those spacers between the controller and the screen are actually legos. The thing labeled VCE is an adapter allowing me to plug a pair of earbuds into the mini HDMI port.
I can highly recommend a Kite Circuit Sword Gameboy build like my own.
It's basically a RPi3+, so has a lot more raw power than the Zero builds like RetroFlag, but still no need for active cooling, fits into an original Gameboy case, and there's lots of batteries to choose from. Mine runs a 5200 mAh, which is charged via USB-C and holds power for around 10 hours.
Costs a bit, and takes a bit of tweaking of the case, but everything is pretty much plug'n'play, apart from soldering the speaker and a mode-button onto the board, but really worth it!
I just completed Links Awakening DX on this machine, before playing the new game on Switch, really enjoyed it.
Maybe you could host your scripts on GitHub and hopefully the community would contributes and help you add new features.
Might be better to have short games that take a couple hours to finish unlocked for a day but maybe longer RPG style games should be unlocked for several days? I'm not sure if your friend likes to focus on RPG's to finish them or if he plays RPG's at all. Maybe RPG's only unlocked over the weekend and have a small handful of unique shorter games unlock each weekday (like different ones every weekday)?
@tr00p3r well the fun part with the officials image is that you can mess with it as many times you like. And through messing with it, you learn how the system functions. Basically learning the basics of retropie. I’ve messed up configs so many times in the beginning, lol. But hen when it comes to 3rd party images made for, let’s say my free play zero gba, it gives me direction to look for issues, instead of just being blind to the complexities that makes retro pie.
The raspberry pie was designed to teach people how to code and configure computers. In my case, I’ve learned quite a bit here configuring my pi’s to my liking. Playing games is just a very fun side effect. Good luck 👍
