Head here first to download the latest release UF2 of picogenesisPlus for Fruit Jam.
Enter RP2350 Bootloader Mode
Entering the RP2350 bootloader is easy. Complete the following steps.
Before you start, make sure your Fruit Jam is plugged into USB port to your computer using a data/sync cable. Charge-only cables will not work!
Turn on the Fruit Jam On/Off switch - check that you see the ON light on so you know the board is powered.
To enter the bootloader:
- Press and hold the BOOT/BUTTON1 button down. Don't let go of it yet!
- Press and release the Reset button. You should still have the BOOT/BUTTON1 button pressed while you do this.
- Continue holding the BOOT/BUTTON1 button until you see the RP2350 drive appear on your computer (in Explorer or Finder depending on your operating system).
- You can now release but BOOT/BUTTON1 button.
Drag UF2
Navigate to the folder where you downloaded the uf2 file, then drag it onto the RP2350 drive.
The board will automatically reboot and PicoNES will launch automatically.
microSD Card Setup
Format a microSD card to FAT32 or exFAT and copy your legally acquired Genesis roms onto it.Â
You can optionally organize your games into folders on the microSD card.

The PSRAM on the Fruit Jam is used instead of flash to load the roms from SD, this makes things run as smooth as can be!
Metadata
Download the metadata pack from the releases page and extract its contents to the root of the SD card. It contains box art and game info for many games. The metadata is used in the menu to show box art and game info when a rom is selected. Press START to view the information. When the screensaver starts, random box art will be shown, bouncing around the screen.
