With the latest firmware updates for Ultimate 64, Ultimate II+ and Ultimate II, these devices support GMod2 cartridge images now! Many of Protovision’s physical games are distributed on GMod2 cartridges. Most recently, we have updated all digital packages to include GMod2 crt files. This includes all of our games you have purchased from us previously via our Online Shop or on itch.io. To access the updates, simply reuse the download links that were provided to you at the time of original purchase.
