The lands of Labrynna and Holodrum cry out for a saviour. The forces of evil are gaining power. The Triforce summons you.
As Link, take up your sword once more to determine the fate of two worlds, in the Game Boy Colour classics. Wield the powers of the Oracles to traverse time and control the seasons. And link your quests to reveal the hidden truth in an epic meta-adventure that is greater than the sum of its parts.
Honestly, I don't know. (I'll find out when they go up in a few hours).
I'm guessing possibly not. That'd require extra work on Nintendo's part, and they can be lazy with this stuff. Probably just the usual rom dump, and you'll have to use the manual passwords like the old days.
On the plus side, they're usually pretty short. 5 characters for the little things, and I think 15 characters or so for the New Linked Game one. Not like the 28 PAGE monstrosity I spent a full hour transcribing for Golden Sun 2. Ugh.
From memory, you beat one game and it gives you a password. When you start up the second game you have the option of putting the password in, which starts a linked version of that game- Sort of a New Game+ . As you play through the second title, you'll encounter some extra stuff that you wouldn't have seen in a 'clean' file. (Which means, if you were so inclined, you can actually play 'clean' Ages, followed by 'linked' Seasons...and then replay in the reverse order to experience the 'clean' Seasons followed by the 'linked' Ages- four separate game experiences, not two! ).
When you beat the second game, the linked ending becomes accessible.
There will be a bit of linking back and forth in the second game, but that's all optional stuff. You'll see what I mean when you get to it. The main link itself, is pretty straightforward.
UPDATE: Just checked the digital manual that comes with the game and checked the linking section. It specifically states that the Game Link function is NOT compatible with this version of the game. Pretty much what I suspected unfortunately. Manual passwords it is. No biggie.
@PogueSquadron - Yeah, the GBA shop's only truly unique items were two rings (one for Ages and one for Seasons) that were just trophy rings. They didn't actually do anything. It additionally sold one random ring and a Gasha seed, I believe. Nothing that can't be found elsewhere in the games.
@TriforceBun - I never knew that about the inaccessible space in Ages. I played Ages first on my first playthrough because everything pointed towards the proper order being Seasons -> Ages, and I wanted to see what happened when you didn't play them in that order.
On my second playthrough, I never finished Seasons to do the Ages linked game. I may try to get back to that eventually.
Regarding the 100% thing, yeah, it's a bit of a bummer, but I always give myself slack for things like that. For example, I've only once linked Metroid Fusion up to Metroid Prime to get the "Fusion Suit" in Prime... I don't do it every time I replay Prime, even when playing for 100%. For some little aesthetic thing, especially one that requires unnecessary hardware, skipping it rarely bothers me too much.
I actually do remember the space in Ages! Well I remember a space somewhere. Thought the map design just panned out that way. I didn't realise (or remember) that you could actually access it by going Seasons > Ages.
