DoubleCherryGB is an open source (GPLv2) GB/GBC emulator with up to 16 Player support, based on the TGBDual libretro core by GIGO and Hii. It emulates the GAMEBOY 4 PLAYER ADAPTER (DMG-07) and also adds 1-16 Player Link Hacks. It's named after the Double Cherry Item from Super Mario 3D World.
Check my website for more information, planned features and compatibility list.
- GAMEBOY 4 PLAYER ADAPTER (DMG-07) emulation
- up to 16-Player Faceball 2000 emulation (1-15 without bugfix-patch, 16 players needs patched rom)
- up to 16-Player Tetris Battle Royal (no modified rom needed)
- up to 16-Player Kwirk Multiplayer (no modified rom needed)
- local splitscreen
- netplay support
- Barcodeboy Emulation
- easy Pokemon online trading (Retroarch 1.17 needed)
Netplay is working. Make sure to have all the same amount of emulated gameboys in your core options.
You can download the core via RetroArch Online-Updater on Windows, Linux and Android. To emulate up to 16 units, use the core options in your frontend.
Retroarch 1.17 is needed, because this feature uses the new netpacket api. only the linkcable data is transfered over network, so you won't see the others players screen.
- set the emulated gameboys to 1 and start or join a netplay.
- a second player can join any time, you don't need the same roms.
go to the cable club and talk to the cable club npc. after both players sat down on the table and you see the please wait! screen, you will experince an big slowdown (up to 15 sec) this is because all the pokemondata is transfered. After that you should be able to trade pokemon.
