Original hardware can be worth it, but the listing price is only the first line. Here is the full bill: repairs, batteries, adapters, and the routes that skip all of it.
Short version
- Retro consoles are 20 to 40 years old, and parts like capacitors and disc lasers can fail whether the machine was played hard or sat in a closet.
- Cartridge save batteries are estimated to last about 5 to 9 years, and replacing one takes a soldering iron and a 3.8mm security bit.
- Basic analog-to-HDMI converter boxes commonly list between about $12 and $26; upscalers cost more and mainly improve picture quality.
- Open-source cartridge readers cost around $100 assembled or roughly $50 as a DIY build, and dumping your own ROMs is legal while downloading them is piracy.
- Official collections and subscriptions deliver old games with none of the upkeep, which is often the cheaper route overall.
Retro gaming has two price tags. The first is the number in the listing. The second shows up later, when a save vanishes, a capacitor leaks, or your TV turns out to have no port that fits anything you own. Here is the full bill, item by item, so you can decide whether original hardware is worth it or whether a cheaper route will do.
The sticker price is only the start
Prices for used retro consoles vary widely by system, condition and completeness, and boxed, tested units command a premium. In our opinion the tested part earns its markup: a seller who confirmed the machine works saved you from buying a decoration.
The sticker price also buys you age. Classic consoles are 20 to 40 years old, and their parts degrade whether they were played hard or sat in a closet. The listing gets you hardware that may be fine, or one failed component away from a repair bill.
| Item | What it costs | What moves it |
|---|---|---|
| Used console | Varies by system | Boxed and tested units command a premium |
| AV to HDMI converter | About $12 to $26 for basic boxes | Upscalers and better cables cost more |
| Save battery swap | One battery plus soldering gear and a security bit | Cheaper if you already own the tools |
| Cartridge reader for backups | Around $100 assembled, around $50 DIY | Building it yourself from a hobbyist microcontroller |
Buying used: ask harder questions
The questions change with old hardware. Instead of “does it have scratches,” ask whether the capacitors have leaked, whether a disc laser still reads games, and whether that expensive cartridge is real. Counterfeit carts have grown more common as prices climb, region locking can stop an imported game from booting, and plastic yellows all on its own.
Before paying, confirm the console powers on, reads games and outputs video. Online, read the shipping and return terms, since those vary by marketplace and seller, and sending a heavy boxed console back costs real money. Buying in person skips the shipping risk but also skips the paper trail.
Repairs: capacitors, disc drives and controllers
Some failures repeat across classic systems. Electrolytic capacitors dry out and leak over decades, causing distorted audio, dim or shaky video, no power, or corrosion spreading across the board. Sega’s Game Gear, the Dreamcast, Game Boy models and the original Xbox, whose clock capacitor leaks on most pre-1.6 units, are frequent offenders.
Recapping, which means replacing those capacitors, is routine repair work. It is still work, and unless you enjoy soldering, paying a repair shop is the realistic option. A console that was already recapped professionally often earns its higher price.
Disc systems bill separately. The PS1, PS2, Dreamcast and GameCube wear out laser lenses and drive motors, so discs spin without reading and trays stop opening. Controllers belong on the list too; worn buttons and ports matter as much as scratches on the shell.
Save batteries: the clock inside every cartridge
Many games from the 16-bit era save to volatile memory kept alive by a battery inside the cartridge. Those batteries are estimated to last about 5 to 9 years, which means a battery that has never been swapped may be near or past the end of its life. Pokemon Gold and Silver are famous casualties, because their internal clocks drain the battery faster than normal play.
The fix is a battery swap, and it is a soldering job. The cells are soldered to the board, so you need a soldering iron plus the right screwdriver: a 3.8mm security bit opens most cartridges, though some games need Torx or tri-wing bits. Replacement cells in sizes like CR1616 and CR2025 are widely available from hobby suppliers.
Heads up
Swapping the battery while keeping power on the pads, the only way to preserve the existing save during the swap, can be dangerous. If you are not confident with a soldering iron, find someone who is.
If a cartridge still works today, dump its save before the battery dies, not after.
Getting old consoles on modern TVs
Modern TVs standardized on HDMI, and the RCA or composite ports many retro consoles use are often missing entirely. Check the back of your display before buying anything; some older sets, and even DVD or VCR players, still have the input you need.
When the port is gone, small converter boxes that turn a console’s analog output into HDMI are the usual fix, and basic ones commonly list between about $12 and $26. Better cables and upscalers that sharpen the picture cost more, sometimes a lot more. Our take: a basic converter is fine for casual play. If you chase pixel-perfect image quality, budget for it up front.
The cheaper routes
Original hardware is a hobby, not a requirement. Two cheaper routes reach most of the same games.
The first is official collections and subscription services, which put large numbers of older games on modern hardware with no batteries, no recapping and no adapter hunt. Whether a subscription earns its fee depends on the catalog and how much you play, as our comparison of game subscription services lays out.
The second is emulation. Emulators are legal. Downloading a ROM someone else uploaded is piracy. Dumping a ROM from your own cartridge and your own console counts as backing up your own games, which is legal. Our guide to emulation and U.S. law explains where the line sits.
If you keep the cartridges, open-source cartridge readers can back up ROMs and save files for around $100 assembled, or roughly $50 if you build one from a hobbyist microcontroller and a custom board. They read NES, SNES, N64, Game Boy, Game Boy Advance and Sega Genesis carts, with adapters extending support to Atari and other older formats.
Whichever route you pick, protect your progress first. Our save backup guide covers every platform, including battery-backed cartridge saves. And if the cheap route wins and you end up playing retro games on a handheld PC, our handheld buying checklist covers what to check before you buy.
Quick questions
Is emulation legal if I own the game?
Emulators are legal, and dumping a ROM from your own cartridge and console counts as backing up your own games. Downloading a ROM someone else uploaded is piracy.
Why did my Game Boy game stop saving?
Games that save use a battery soldered inside the cartridge, and those batteries are estimated to last about 5 to 9 years. When the battery dies, the console can no longer keep or overwrite saves.
Do I need an expensive upscaler to play retro games on a modern TV?
No. Basic converter boxes that turn a console’s analog output into HDMI commonly list between about $12 and $26, and they are fine for casual play. Upscalers cost more and mainly improve picture quality.
Can I keep my save when replacing a cartridge battery?
Only by keeping power on the battery pads with a secondary power source while you swap, which can be dangerous and takes real care. If the cartridge still works, the safer move is to back up the save first.
