Hello! I am new to Pico-8 and I just purchased an RG35XX Plus solely for Pico-8 since it runs natively. I installed muOS PIXIE on the device, downloaded the Raspberry pi files for Pico-8, put the .zip file in the ARCHIVE and installed it with Archive Manager. All of that seemed to work fine. However, I also created a separate folder under ROMS called "pico8" and in there, as instructed, I included a "dummy file" called "Splore.p8". I also put a .png cart file in there to test. When I put the microSD back into the device and go to Explore>pico8 it says "No Content Found..." Can anyone tell me what I've done wrong?

It sounds like you're almost there with getting Pico-8 working on your RG35XX Plus with muOS PIXIE! The "No Content Found..." message usually points to a few common issues. Let's troubleshoot them:

Here's a breakdown of what might be going wrong and how to fix it, assuming you've followed the muOS PIXIE instructions for Pico-8 installation:

1. "Splore.p8" Dummy File Location and Naming:

• Crucial Point: The Splore.p8 file must be in the root of your pico8 ROMs folder. It's case-sensitive.
• Check: Double-check that the file is named exactly Splore.p8 (with a capital 'S') and not splore.p8 or Splore.p8.txt (if your operating system is hiding extensions).
• Placement: Ensure it's directly inside your ROMS/pico8 folder, not in any subfolders within pico8.

2. Cartridge File Format and Location:

• Pico-8 Cartridge Types: Pico-8 cartridges come in two main forms:
  • .p8 files: These are plain text files that contain the game's code and assets.
  • .p8.png files: These are special PNG image files that embed the .p8 data within them. They often look like regular image files but contain the game.
• What you put in ROMS/pico8: You should be placing either .p8 or .p8.png files directly into your ROMS/pico8 folder (alongside Splore.p8).
• Check the Test Cartridge:
  • Extension: Make sure your test cartridge file has either a .p8 or .p8.png extension. If it's just a .png without .p8. before it, it's likely just an image and not a Pico-8 cartridge.
  • Source: Where did you get this .png cart file? It needs to be a legitimate Pico-8 .p8.png cartridge. Many Pico-8 games found online will be in this format or as .p8 files.

3. muOS PIXIE Scanning/Refresh:

• Database Scan: After adding new ROMs, some frontends require a refresh or a scan of the new content. While muOS is generally good at detecting new content, it's worth a shot.
• Try restarting your RG35XX Plus. A full reboot can sometimes trigger the system to re-scan your ROM directories.

4. Pico-8 Installation Integrity (Less Likely if you got to "No Content Found..."):

• Did the Pico-8 executable install correctly? The "No Content Found..." message typically means the system found the pico8 folder and tried to look for content, which suggests the Pico-8 emulator itself is at least partially recognized. However, if the Pico-8 installation (the one you put in ARCHIVE) didn't fully complete or if there's a corruption, it might not be able to identify the .p8 or .p8.png files as valid content.
• Re-install Pico-8 via Archive Manager: If all else fails, you could try removing the Pico-8 installation via Archive Manager and then re-installing it.

5. SD Card Issues (Rare, but possible):

• Corruption: While unlikely if other ROMs are working, a corrupt SD card or a bad sector in that specific area could cause issues.
• Re-seat the SD card. Sometimes, simply taking it out and putting it back in can help.

Let's Summarize the Key Checks:

1. ROMS/pico8/Splore.p8 exists, is named exactly Splore.p8 (case-sensitive), and is directly in the pico8 folder.
2. Your test cart is in ROMS/pico8 and has a .p8 or .p8.png extension (e.g., mygame.p8 or mygame.p8.png).
3. The RG35XX Plus has been restarted after placing the files.

If you can confirm these points, you should be seeing your Pico-8 games listed! Good luck, and welcome to the wonderful world of Pico-8!
