The ending screen that the Nerd was unable to read (because it was in Japanese) loosely translates to: "Emergency order! Using a new power, Destoron has revived and become even more powerful. Retrieve Rodimus' Energon Cube and destroy Destoron once more. Scramble! Ultramagnus!"
The ending screen the Nerd receives was actually 1 of 2 available. The second one reads, "Magnus wa saigo no tatakai ni katta. Shikashi aratana tatakai ga menomaeni sematte iru! Vuke Rodimus! Attack! Rodimuscomvoy!" Which translates to: "Magnus won the final battle. However, a new battle approaches! Go, Rodimus! Attack! Rodimus Convoy!"
