GameEx recently confirmed today that the v1.7 Update for the T-Games NeXT will bring with it a new Menu System that they call 'Glacier'. Glacier allows users to change some of the NeXT's options, Open an Inserted Folder and play 8 Pre-Installed (and customizable) tunes from Controllinator 1. When a Folder is in Play, users can then get back to the Menu by using the Direct-Control shortcut of R1 + L3.
The update also brings with it a Hard-drive, where users can put on 8 of their favourite tunes, and then access them via the Menu.
The NeXT v1.7 update is being planned to be released on August the 21st - The NeXT's 1st anniversary (after a long period of beta testing).
