Retro Jam Multi-Emulator
As the Pico RP2350-based game console emulator field grows doesn't it feel limiting having to pick just one? Fear not, Frank Hoedemakers has created a new multi-emulator launcher called Retro Jam that solves this very issue!
Retro Jam combines the emulators Frank has ported to Fruit Jam into a single drag-and-drop .UF2 file with a launcher for these systems:
- Nintendo NES (including save states)
- Nintendo Game Boy
- Nintendo Game Boy Color
- Sega Master System (including save states)
- Sega Game Gear (including save states)
- Sega Genesis
Plus, there's a .wav player for just jamming to your favorite tunes.
You can see the Retro Jam in action in this video below:
Software Installation
First, download the latest retroJam release here.
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 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.
- 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 retroJam will launch automatically.
microSD Card Setup
Format a microSD card to FAT32 or exFAT and copy your legally acquired game roms and wav files onto it.
You can optionally organize your games into folders on the microSD card.
Metadata
Download the metadata packs from the releases page and extract their contents to the root of the SD card. These contain 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.
