Which retro handheld accessories are genuinely useful: cases, screen protectors, chargers and batteries, storage, link cables and adapters, cleaning kits and mods, plus what to avoid and safety tips.
The right accessories make a retro handheld more comfortable, safer to carry and longer-lasting. Many others are unnecessary. This guide covers the accessories most players find worthwhile, for both original consoles and modern retro handhelds.
Protection
- A hard-shell case: the single most useful accessory. Choose one that fits your device, with room for a cable and a few cartridges.
- Screen protectors: tempered glass or film protectors for modern devices prevent scratches. For original consoles, replacement screen lenses are cheap if the old one is scratched.
- Cartridge cases: protect labels and contacts from dust and damage.
Power
- Chargers: modern handhelds usually charge by USB-C. Use a reputable charger with the correct output; cheap unbranded chargers can be unsafe.
- Rechargeable batteries: for AA-powered originals, quality NiMH rechargeables save money and waste.
- Rechargeable battery mods: kits replace AA compartments with lithium-ion packs and USB-C charging. Choose reputable kits with protection circuits, or have them fitted professionally.
- Power banks: useful for travel. Remember airline rules on carrying lithium batteries in hand luggage.
Storage
For emulation devices, a quality microSD card from a reputable brand, bought from a trusted retailer, avoids the slowdowns and corruption common with cheap or counterfeit cards. Many devices ship with low-quality cards; replace them and keep a backup of your saves.
Connectivity
- Link cables: for original Game Boy multiplayer and trading. Check which models a cable supports, since connectors changed between generations.
- Video output: some modern handhelds connect to a TV via USB-C or HDMI docks; check compatibility first.
- Controllers: Bluetooth controllers suit devices that can be used as home consoles.
- Cartridge adapters: FPGA handhelds use adapters to play other systems' cartridges.
Comfort
- Grips: add-on grips can make small handhelds easier to hold for long sessions.
- Headphones: check whether your device has a headphone jack or Bluetooth audio; Bluetooth adds latency that can affect rhythm games.
Maintenance
- Cleaning cartridges: isopropyl alcohol (high concentration) on a cotton bud cleans cartridge contacts. Let it dry fully before inserting. Avoid abrasive methods.
- Security bits: Nintendo used tri-wing and gamebit screws; inexpensive screwdriver sets let you open consoles and cartridges.
- Replacement shells and buttons: refresh worn consoles. Keep original parts if you might want to return the console to original condition.
Popular mods for original handhelds
- Backlit or IPS screens: make original Game Boy models much easier to see. Some kits need trimming of the shell; follow guides carefully.
- Audio amplifiers: improve volume and reduce noise.
- Recapping: replacing old capacitors, essential for many Game Gears.
Modding needs soldering skills for some kits. If you're inexperienced, use a reputable repairer. Mods can lower the value of rare consoles to collectors.
A sensible starter kit
For most people, a good case, a quality charger or rechargeable batteries, a reliable microSD card (for modern devices) and a basic cleaning kit cover nearly everything. Add mods and extras only when you know you need them.
Storage at home
Store consoles and cartridges away from damp, heat and direct sunlight, which fade labels and plastics. Remove AA batteries from consoles kept in storage to prevent leaks and corrosion.
What to skip?
- multi-game cartridges and preloaded devices containing unlicensed games;
- cheap chargers without UK safety markings;
- novelty accessories you'll rarely use.
Safety
Lithium-ion batteries can be dangerous if damaged or poorly made. Stop using swollen batteries, charge on hard surfaces, and buy from reputable sellers. Electrical Safety First offers guidance on charging safely.
