HERE BE SPOILERS: WARING! WARING! WARING!
Episode 7 "Bid Farewell to the Earth": The party thrown aboard the Yamato is based on the Earth-bound, "Line-crossing Ceremony" aka "Crossing the Line", the long-held martime celebration of traversing the equator. In 2199, this is for crossing the Heliopause, the outer-most area of our Solar System. This features elements from Episodes 10 ("We Will Return") and 14 ("Octopus Star Storm") of the original 1974 series.
Episode 8 "When You Wish Upon a Star": Combines some elements from Episodes 9 ("Asteroid Belt"), 11 ("Desslok Mines"), and 12 ("The Sea of Fire") of the 1974 series. Instead of being a complete invention of Dessler, the living "Ectogas" was instead created by manipulating a primordial lifeform from the Mirbelia Star System, and unleashed against the Yamato at Gliese 581, a red dwarf star approximately 22 light years from Earth.
The Dessler Mines in the original 1974 scenario, have been changed into "Dessler Torpedos". These special weapons are equipped aboard Shultz' flagship to drive the Yamato into the trap at Gliese 581. Thus eliminating the "magnetic space net", and combining the Gamlias tactical operations from Episodes 11 ("Desslok Mines"), and 12 ("The Sea of Fire") of the original.
Episode 9 "A Clockwork Prisoner": Original Story. The reactivated Gamiloid, captured in Episode 5 of 2199, is dubbed "Oruta", ("オルタ", previously rendered as "Orta"), which is actually derived from the Japanese rendering of the English word, "Alternative" (from his designation as an "Alternative Reboot"). So, this automaton should therefore be rendered as "Alter" in English.
Episode 10 "The Cosmic Graveyard": Incorporating elements from Episodes 13 ("The Gamilon Pilot"), 14 ("Octopus Star Storm"), and 15 ("Galactic Whirlpool") of the original. When the Yamato enters the dimensional rift, it passes through a graveyard of ships. Eagle-eyed viewers may spot, among the myriad of derelict spacecraft, a lone Devastator — the horseshoe crab-shaped attack fighter belonging to the Comet Empire!
Aboard the trapped Gamlias Meltoria Cruiser EX-178 are Commander Valess Rang (ヴァレス・ラング), a "2nd Class Gamilan" from planet Zalts, and a pure-blooded Gamilan, Captain Palen Nerge (パレン・ネルゲ), of Dessler's Protection Squad (essentially, the Schutz-Staffel aka the SS). Tensions arise between the two men, when Rang decides to reach out to the crew of the Yamato, so that both ships may make it out of the dimensional rift, alive.
Lastly, the ecological restoration device offered to Earth by Queen Starsha of Iscandar, originally dubbed the "Cosmo Cleaner" or "Cosmo Cleaner D" ("Cosmo DNA" in the Star Blazers version), is now to be called the "Cosmo Reverse System" (コスモリバースシステム). This must sound much better to Japanese ears...
