Hello! I whipped up this stupid meme in about an hour..
So let me tell you how it works!
Audio
So, I used @luchak 's Picotron PCM Driver: https://www.lexaloffle.com/bbs/?tid=141655
It uses Unsigned 8bit PCM @ 44100KHz, so I used audacity to export my normal audio file as a Raw (headerless) 8bit Unsigned PCM Audio file at 44100KHz.
I then dropped that into my cart, and that's that.
As for playback, here is my code:
include "pcm.lua"
audioraw = nil
sample = 1 -- Index in terms of frames (left and right samples)
function get_audio(n_samples)
local sound_left = userdata('f64', n_samples)

Hello! Welcome to TronStore!
Its a small appstore I just made for Picotron.
It loads carts from bbs:// and displays them somewhat neatly.
You can run apps sandboxed without installing, or you can install them!
When you install an app, it installs it to /appdata/TronStore
The code is a bit jank, but if you'd like to improve upon this code, go right ahead!
You can browse sandboxed / on web, but installation and running only works when TronStore is installed.
Also, it's pretty slow, since it fetches every BBS entry in the current tab, so it won't redraw whenever its loading bbs entries.

Mod Manager
Mod Manager is a simple tool for modifying your system!
Installation
Simply install the cart to your system and run it! The first time you run, you will be prompted
to select a mod path. This is where Mod Manager will look for ".mod" files to load.
Next time you run, if there are any ".mod" files in that directory, they will load it!
Command Line Usage
modman - Starts Mod Manager and loads mods
modman --config - Opens Mod Manager Configurator
modman --force - Reloads Mod Manager even after running for the first time in the session
modman --compile [path/to/uncompiledmod.txt] - Compiles mod and stores it in "compiled.mod"

"Open in Terminal" in FileNav!
Here, you can see it big and clear, a "Open in Terminal" option in FileNav!
How did I do this?
By modifying "/system/apps/terminal.lua" and "/system/apps/filenav.p64", you can do this yourself!
Before modifying anything in "/system", if you want it to stay after reboot, check out my Localize System Tool!
NOTE: Localizing your system folder can be very dangerous. It can brick your Picotron installation, and even allow malicious carts to install themselves and harm your actual OS drive. This demonstration wont do as such, but be careful when installing untrusted carts. This will also keep your system at the same version that it was localized at, and you will need to unlocalize your system to update, and you will lose all of your changes
An alternative to localizing your system is sedish.

Localize System - A small tool for managing and saving your /system folder!
Normally in Picotron, when you make changes to /system, they go away on reboot. This is fine, and actually ideal, because any errors could easily brick your Picotron installation, or even allow malicious programs to gain kernel permissions (THIS IS VERY BAD. THEY COULD ACCESS YOUR ACTUAL OS).
