Description

A test program to write to Virtual Boy flash carts during QA to quickly test for hardware faults.

Boots directly to a test screen which writes and then reads a value to/from SRAM and outputs the result on the screen. Also tries to initially reads SRAM to see if a previously written value was held.

Outputs some audio clues as well so peeking into the VB isn’t even necessary for testing:

  • Double success sound: Successful read/write test and previous value could be read
  • Single success sound: Successful read/write test, but no previous value could be read
  • Failure sound: Read/write test failed

Contains a low battery indicator and an alignment check screen that can be activated with the Select button.

There are versions for various flash carts:

  • FlashBoy Plus
  • HyperFlash32
  • HyperBoy
  • HyperBoy Plus
