Some side mention about Zelda 1's SFC remake as a Satellaview project on a stict timer developed by interns, but with dungeons themed as ST GIGA (named after the company providing the radio service), I guess? It also did the male/female protagonist choice years ahead of what some gaming sites would like to credit.
And since you're doing Zelda 2 as well, there's that SNES tech demo screenshot showing off kanji, and some of the music for that cancelled game (alongside beta SMW graphics) in a leaked NoA internal technical support cartridge.
That the extra NPC sprites in Zelda 2's English edition were just possible thanks to Nintendo over-writing the kana font? Explaining their obsession with righting that wrong with the canned SFC remake which has room in the VRAM this time for kana, the improved lady sprite (also seen in that screenshot), the kanji, and then some more!
The Loto joke involves, well, Loto (Dragon Quest), Zelda 2 (Here lies Loto), Final Fantasy (Here lies Link / Erdrick), and Tengai Makyou 2 (a whole graveyard with Loto, Mario, and Adol of Ys fame). The whole area in Zelda 2 was removed in the US version and the text replaced internally with "NOTHING.".
If you could make up an excuse to fit in a mention of Marvelous Mouhitotsu no Takarajima (originally a SNES-CD game with FMVs using the Zelda 3 engine, Eiji Aonuma's very first game then was split to a SNES game and two BS-X spin-offs - a GC revival was eventually dolled-up as a Zelda game, namely Navi's Trackers), please do, by all means.
