Install Razoola's Universe BIOS into the Neo Geo AES console. This will unlock many features of the Neo Geo AES, more information about this can be found here. The BIOS code itself is free; you are not paying for the code. You are only paying for us to replace the stock BIOS with an EPROM programmed with this new BIOS.

A comprehensive install includes the following:

  • desolder the old BIOS (it will be sent back to you with the console)
  • install a 40 pin socket to hold the new BIOS (for easy future upgrades)
  • program an EPROM with the latest version of the free universe BIOS and install in the system
  • The centre post of the top shell will be cut off. It serves no real purpose and has been known to crack the main PCB.
  • system cleanup and verification


  • The EPROM and socket will be provided as part of the install
  • A Neo Geo AES system must be provided in good working condition
  • If you plan on using RGB out of your AES system, we strongly recommend the Neo Geo AES RGB bypass mod. Ask us about our discount if we provide both services at the same time.
