Backing Up Virtual Boy Games

Nintendo’s red stereoscopic oddity sold for barely a year and left a library of just over twenty games — which makes preserving the carts you own genuinely worthwhile. They’re small, unencrypted cartridges, so a reader copies one to a tiny .vb file. Start with the ground rules: own it, dump it yourself, keep it private.

Media
Cartridge — small, unencrypted ROM.
Hardware
A Virtual Boy cartridge dumper — a purpose-built reader for the console’s connector.
Output
.vb.
Typical size
512 KB – 2 MB.
Save data
Virtual Boy Wario Land and a few others use on-cart saves the dumper reads too.
BIOS
Not needed. The OWL player’s Virtual Boy core needs no firmware file.

What You Need

  • A Virtual Boy cartridge dumper. The system is niche, but the preservation community has built dedicated readers that copy a VB cart’s ROM over USB. Because the library is so small, one dumper handles essentially everything you might own.
  • Isopropyl alcohol and swabs — clean the cartridge connector before reading.

Dumping, Step by Step

The Virtual Boy dump: (1) a small unencrypted cartridge, (2) read by a USB dumper, (3) written out as a tiny .vb. Diagram: NDEVR.
  1. Clean the contacts with isopropyl alcohol.
  2. Read the cartridge in the dumper.
  3. Verify. Check the file against the No-Intro database — with so few titles, a full set is easy to confirm.

A Whole Library in a Pocket

Preservation’s easy win

The Virtual Boy’s commercial library is small enough that a complete, verified backup of everything you own is a realistic afternoon’s project — and because the hardware is fragile (the displays are known to fail), a clean dump may outlast the console it came from. Back up the carts while the reader is out.

Playing Your Backup

Upload Game.vb to your OWL media library and it appears in the Games collection — the player’s Virtual Boy core renders its red stereoscopic display in the browser (as 2D, or anaglyph with the right settings), save states synced across your devices inside your own end-to-end encrypted storage.
