The BIOS and homebrew titles
Many original homebrew games required the use of a bypass cartridge or game with built-in bypass routines, such as Protector SE or Battlesphere Gold.
The routines to properly sign homebrew software are now available, allowing the boot of homebrew software on unmodified Jaguar CD consoles, but older original titles still need a bypass option.
If you don't have access to a bypass cart, replacing the stock BIOS with a 27c020 programmed with an altered BIOS will allow booting of all software. A kit to replace the factory BIOS is available here. If you have a burner, the BIOS image may be downloaded from this page.
