before you toss aside your Serial Port adapter, the GDEmu can actually be used in conjunction with this dated device to give your Dreamcast some added oomph! For those unfamiliar with the adapter, some homebrew software known as Dreamshell was developed to grant the console its very own operating system equivalent. This allowed the aforementioned loading of games via SD cards through the adapter, amongst other things such as backing up original game discs in their rawest form. While these functions may no longer be needed, placing Dreamshell onto your GDEmu’s contents allows you to do various other little tweaks to your system, along with being able to back-up and restore save games on your Visual Memory Units. And before we leave this point, those still nostalgic about the VMU should look towards putting Dream Explorer onto the GDEmu too - a disc full of all the VMU mini-games and functionality to restore them.
