The amazing USB-C gadgets that play old Nintendo cartridges

Key Points:

• Epilogue Operator devices enable reading and writing save files on real Game Boy, Game Boy Color, Game Boy Advance, and Super Nintendo cartridges via USB-C, allowing users to back up and play classic games on modern devices like PCs, Steam Decks, and phones.
• The hardware works by dumping cartridge ROMs to a computer and running them through emulators, with Epilogue's Playback software providing seamless gameplay and automatic save synchronization back to cartridges.
• While the devices offer unique features such as savegame transfers between original hardware and emulators, and mouse/light gun emulation for SNES games, they have limitations including sensitivity to cartridge condition, incompatibility with multi-game flashcarts and Super Game Boy, and inconsistent counterfeit cartridge detection.
• Epilogue contributes to open-source emulator projects and has developed features like a custom CRT filter and plans for online multiplayer, enhancing the retro gaming experience beyond simple cartridge reading.
• The finite lifespan of original cartridge batteries means many older save files, especially on second-generation Pokémon games, may already be lost, making backup devices like the GB Operator valuable for preserving progress before battery failure.
